Show HN: How good is your color vision? Find out in my new game

I got some confetti after an unknown number of clicks, but this doesn't answer the question of "how good is my color vision"

Well could you see the multicolored confetti?

lol

Yup. I got all but one correct. Confetti but no score.

How did you know it was all but one correct?

The game beeps if you get a guess incorrect.

Yes but for at least some of us, the confetti was seen on the round where we used our last guess. So we are wondering how the commenter knows there weren't more rounds. Did you get confetti on a round that you know to have guessed correctly?

Edit: I just played again and am confident that my guess before the confetti was correct.

I definitely guessed the last one correctly, because it was obvious to me, as were nearly all of them.

I'd have to go back through it and deliberately fail on the last one to confirm, but I assumed I'd get the error beep on the past one if it was wrong.

It would be nice to see:

How many questions there are in total. For e.g., question 1/25 leads to 2/25, etc.

How many were answered correctly. (There are a couple that I'm not sure if I got wrong or was lucky in guessing.)

How one's score compares to the baseline average. (Not to other players, because other players could be re-taking the test many times or cheating. Take 25 random people, have them play the game once with no training or coaching, and use that as the baseline.)

Thanks for the feedback! Since the game is still in the early version, my initial idea was to keep it simple, to see if people will play it at all, but I’m definitely planning to add features like showing the total number of questions/statistics. Appreciate you playing!

What would be really cool, is knowing what was supposed to be different.

That is, how was it different? I got all but 1, and it'd be neat to know what primary colour was different. Then you'd know what your eyes have issue with.

Even neater would be a further series of tests on that weakness.

(Some people, mostly some women, have an expressed gene where they can detect 4 primaries. Wonder how that works here...)

Just played again. A nice touch would be the ability to play with the confetti as it falls. Just a thought.

(And how good is the color reproduction of your monitor)

If you look at this on a TN screen it's going to be a lot different than something like a nice OLED. (Not that OLED doesn't have issues, but colors are great on them)

And if you're in sRGB mode or some kind of extended color space. And how the OS is configured.

So I completed it. Did I do well? No metric? Confused.

It's fun! I'd love to see a "final score" - both number correct/total number, as well as the time elapsed.

I got the confetti at the end, what did I find out?

There were 2 I had to just start hitting squares until I got it right, and one of those I did notice the different one once I started tapping, I probably could have spotted it if I was more intentional. This seemed significantly easier than the standard Ishihara tests for me, which makes me question how well it works to judge color vision. I’m red/green color blind and the Ishihara test usually have me skipping a significant number, because I don’t see anything… to the point doctors bring out a basic red, yellow, green cards to make sure I can see traffic lights.

I breezed through this test, with the exception of maybe one or two squares.

I’m red/green colorblind but constantly doubt if I am. Every few years I ask an eye doctor if I’m colorblind. The last time I did this they only went through a few pages of the Ishihara test before closing it and saying, “Yep, you’re colorblind.” I’m also able to read reverse Ishihara tests which my non-colorblind friends can’t.

I don’t think I’ve ever called something red when it was green or vise versa when someone’s asked me to identify its color. Red and green look quite different to me! However, I cannot for the life of me spot my dog’s red frisbee in green grass, or pick out a red character among a bunch of green ones without looking at each character. These are both things people in my family with perfect color vision do just fine and without difficulty.

> Red and green look quite different to me! However, I cannot for the life of me spot my dog’s red frisbee in green grass, or pick out a red character among a bunch of green ones without looking at each character.

This is basically a textbook description of standard red green colorblindness. Whenever you find yourself doubting whether you actually are red/green colorblind, just go strawberry picking with friends.

Yep. Whenever I say I am colourblind, people show me a tree and ask "what color is it?". And I have to explain that I know what red/green is.

An example I give is red flowers in green grass: I may not see the flowers at all unless I go very close.

Another one is while climbing indoors: say there is a purple route next to a blue one. Some handles I will clearly classify as blue, some clearly as purple, and some in the middle I won't be able to classify. But non-colourblind people will clearly be able to classify them all.

> Whenever you find yourself doubting whether you actually are red/green colorblind, just go strawberry picking with friends.

I'm extremely bad at picking fruit in our garden. I'll go to pick the raspberries, strawberries, or peppers and only find a few. Then my wife will go out and find several times my haul from the same plants.

It does seem like they use darker/lighter shades instead of redder/greener/bluer at the same intensity but I don't have the means to check if that's true

Feedback: - At end of game show statistics correct/incorrect

- At the end of game show which particular color weaknesses were identified

- Show progress meter (1 of 20)

- I have a red/green weakness and I expected to run into issues. One of the greens was hard to differentiate but I still got it right. I expected it to be harder. Perhaps look up exact pallets for different color perception issues and use those.

Interesting tool.

It needs a couple of options.

One button option should indicative the person is unable to see any difference, and move on, a second button option should be the box they indicated they were sure is a different colour was not right, and move on. Additionally the tool should map the position of the box when they were sure but were wrong, and keep a record as the person works though the game, just in case their screen is not perfect. Perhaps even come back to the same colour scheme but put the different colour in a different part of the screen.

It shouldn't be forgotten that people actually tune into slightly different colours given some time - fruit and vegetable graders who visually inspect, and those who are working hard to purchase the just right fruit and vegs, find given time and practice, they'll slowly learn to perceive the very minor differences in certain shades or hues.

Edit twice, a couple mins later and another couple for additional clarification.

I think the screen can definitely be a factor. I'm using a monitor with a TN type panel, and the viewing angle will change the amount of contrast which makes a difference in the later stages. Some would have been impossible to pass first time without shifting my head, even if my eyes are up to the task.

Thanks for the feedback! My initial idea was to make something super simple for children, this is why I didn't add any buttons (there are 0 buttons in any of my games on my website, except for "start" button). But let me see if there are any alternative solution.

Neat, but it doesn’t answer the question. It would be nice to see how well you scored compared to others.

Thanks for the feedback! I get what you mean. Since the levels aren't infinite, my initial idea was that anyone who can spot all the colors will finish the initial version of the game. But I'm planning to add score comparisons if people like it. Appreciate you playing!

Time taken too, since this is a game it adds a bit of challenge to it beyond "you can/can't see all the colors".

Wait, so is seeing the confetti at all mean you "won"? What does that amount to?

Why do I need audio for a game about colors? I had to read the comments here to figure out why there was no score or indication of right / wrong

A web chart (https://blog.zohowebstatic.com/sites/zblogs/images/analytics...) that shows your % score around a color wheel would be very cool

Had no trouble with these except for the three or so panels of bright green which were almost impossible to distinguish. I got the confetti in the end but wasn't paying attention to beeps so not sure if I got any of the bright greens right.

I'd like a progressive or training mode.

I'd also like the hex codes and name of the color to pop up somewhere, maybe part of the training mode?

I would love to use this app to practice my color name recognition, not just seeing if I can differentiate them.

As someone who has been offered similar buy-outs, the one presented here is a poor deal. I would not have taken that one unless I already had a job waiting for me.

Wrong post?

on the home page they were next to each other, i thought i had clicked on the wrong one ;)

Yes, wrong post. Thanks.

I'm assuming I did well since I finished it in under 30 seconds. Then again, I trained myself to notice even a difference of 1 in a channel for a RGB pixel.

Are any of them supposed to be hard? I think only the last 2 were even remotely challenging.

It doesn't tell you how you did. Just a bunch of confetti at the end.

I got all correct but had to stop and think for the green ones.

Same, the a couple of the green ones were quite subtle. Not sure if that's due to the developer, human vision, or the how color rendering works.
