Me again.
In a fresh project, at Playmaker 1.9.5f3, the color palette still remains hurt by a non-fidelity bug of some kind; the "Legacy" theme type that had an old school gradient shadow to give some kind of roundness to the states now simply applies a slightly darker shade over a state's title, whereas the "Flat" is slightly less darker. One can compare with 1.8 and see the big difference. There is in fact nothing really "legacy" about it really against the flat (design) that just darkens things too, but just a little bit less.
Now why this is being done is simple to guess: with one single color set, a state can have three of them depending on what needs to be colored: the parent color as defined in the color palette, which will be used for links if the user wants them to be related to the state color; plus two variants, one darker for the state name written in a white font, and one paler for the exit transition event written in a dark font.
This avoids the state name to be impossible to read no matter what color is selected. But this means it is impossible to use vivid and bright colors. Thus the default orange, no how matter how bright and peppy in the settings, will always be a dull brown in the Graph View, while the applied default yellow will look like a foul puddle of piss more than anything else.
This "autotuning" of the colors, introduced around the first versions of 1.9, is just a sad thing really.
Why can't the states be of the color as seen in the color palette?
Why can't the Legacy style simply cast a gradient shadow over the lower part of the state?
And why not make that an option, this darker veil, to automatically darken the state name zone if users are worried that some colors would make the white text impossible to read? That would be the users' faults anyway for setting colors that would be too bright and pale but at least they would remain in control of how things are going to look like in the Graph View.
The transitions' paler variant of the color palette isn't causing any trouble, so this one can probably stay the way it is, although perhaps some users would want the whitening of the transition zones to be tickable off too?
Edit: Soon 5000 views for this?
