My quick and dirty trick is to set an alpha=0.8 to soften the default colors. It always looks better.

I don't mind the default colormap (parula). If I'm using the color for any sort of dimension then I start to care about the colormap choices. Perceptually uniform and colorblind agnostic choices are important for any sort of publication, and arguably a starter for any sort of accessibility considerations.

Take a look at colorcet. https://colorcet.holoviz.org/

The four uniform colormaps that the page references are the value that I'm referring to. Viridis, plasma, inferno, and magma. I don't want a huge selection of colormaps, just a few good ones.

Here is where to get them on the file exchange. This really ought to just be folded into MATLAB proper releases somehow.

Indeed that does make charts look better. I do this for grid line:

ax.set_axisbelow(True) ax.grid(True, alpha=0.3)
