I use the Freeform app quite a lot for doodling on my iPad. It’s not a perfect app, but it works for my needs, those needs being “recapturing that childhood habit of idly doodling on grid paper”. However, I’ve noticed something that I now can’t un-notice.
There are five colors available in the Markup toolbar — red, yellow, green, blue, and black.
There’s also a color picker pop-over, which by default also has five swatch colors — again, red, yellow, green, blue, and black.
However, as the observant among you may have already noticed:
These are not the same colors.
Compare the toolbar colors (top) with the popover colors (bottom):
I initially thought this might be some mis-handling of color spaces, as Apple displays generally use Display P3 and a mis-conversion between sRGB and Display P3 felt plausible? But playing around with the colors I couldn’t get them to line up in a manner that might confirm that theory. If you’d like to poke around with it, the colors are as follows (as RGB triples in the P3 space):
|red||232, 70, 74||235, 77, 61|
|yellow||247, 210, 84||247, 206, 70|
|green||121, 212, 117||100, 196, 102|
|blue||59, 124, 242||40, 95, 244|
|black||0, 0, 0||0, 0, 0|
