Color picker broken in High Sierra

[eboltz]

While it is possible to pick a color BEFORE creating an object like a line, curve or text, it is no longer possible to change an object's color or to pick a color other than black for the canvas. Any attempts to change colors of objects or the canvas immediately revert to black.

GraphSketcher fills a needed space for presentation graphs so I'm hopeful this can be easily corrected.

I also observe this issue.

Found a workaround by using color picker swatches. It's not entirely reliable: certain colors refuse to be picked. (Must be a function of their internal representation, colorspace, or something.)

Same problem here :(

Hello, Did anyone find a solution or fix the bug concerning this issue with the colour picker not working in High Sierra?
Any help appreciated :)

Instead of picking a predefined color, I started using RGB sliders option of the mac color picker to choose customized colors and so far it seems to be working.

Thank you – just tried that and it works!

The problem is in OQColor.m in the OmniQuartz framework. The method colorWithPlatformColor fails to match a colorSpaceName and returns blackColor every time. In my case, I was getting NSCustomColorSpace, which wasn't being handled. Instead of returning blackColor every time at the bottom of the function, I just returned a linear RGBA color of what was passed in. That seems like a better default choice.

'Classic Crayons', 'Web Safe Colors' and 'Developer' palettes of 'Color Palettes' tab of the Color Picker seems to be functional too (on Mojave 10.14.6).
