cmap's Issues

Shameless plug to cmap_picker

Hey,

Just wanted to share this tiny function I just wrote to help pick up a colormap from an image. I saw you had something related (get_from_img.m), and I had myself written something similar a while ago too (make_c_map_out_of_screenshot.m), but I think this is more user-friendly:

https://github.com/briochemc/cmap_picker

Not sure it'll be useful to you, but if it is then that's good!

Closing this right away because it's not an issue with your repo :)

ColorShemes.jl colormap suggestions

Just wanted to share a link to the ColorSchemes.jl catalogue (for Julia). Just thought you'd be interested in it as a potential resource because copying a colormap here would then only require a little copy-pasting.

Colorbrewer colormap orientations are inconsistent

Just noticed that out of the diverging colorbrewer colormaps listed here

Only the first and last ones are oriented in the same way that https://colorbrewer2.org/#type=diverging is. In other words rdylgn, piyg, and prgn should be reversed to match the original colormaps. Note that I have not checked other colormaps!

I think colorbrewer chose these orientations because we traditionally expect red-ish colors to represent the most positive values (i.e., at the top/right/end of the colormap).

---

That being said, colorbrewer's naming convention itself is not consistent, e.g., RdBu starts with blue (at the bottom) while PuOr starts with orange purple (edited)...

So maybe it is worth correcting colorbrewer's inconsistency here and only having names that match the color order? I.e., RdBu would go from red to blue. An ideal solution is probably to also allow for BuRd in this case, which would go blue to red. What do you think?

Bug in MAKO cmap

MAKO colormap contains light colours on dark end of the colour range.
