Hubble is very brown-y, and Webb is much more blue.
But these are false colors, and they capture different light. It has to be an artistic decision to make it blue, vs brown, so does anyone here know the rationale? Is it to distinguish the different provenance? Is the color shift indicative of the captured spectrum difference? Is it a convention of the sensor? Is it a 2020s fad?
Hubble uses visible light and I prefer this image from an artistic standpoint as it seems to capture depth better.
> These images are a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument. Several filters were used to sample wide wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F770W, Green: F1130W, Red: F1280W.
Chasing some numbers up, it looks like they've made the wavelengths around 20 times shorter to bring the picture into the visible spectrum.
