Color Picker doesn't match the color

PostWed Jul 28, 2021 4:46 pm

I'm using Resolve 17.2.2 on a iMac Pro with MacOs 10.15.7

Whenever I sample a color for a colored solid it doesn't actually match the color it should.
Has anyone else experienced this? Is it an issue with project setting?

EDIT:

Turning on the 10 bit viewer option for Macs in Preferences solved the problem.

Been that way since V11. I gave up trying to fix it.

Simply make a solid color of 128, 128, 128 and eyedropper it.

It changes luminance each time it is sampled.

Preferences >General>System menu. Page 94 of the latest manual.

"Use 10-bit precision in viewers if available: This checkbox only appears on Mac OS X 10.11 (El Capitan) and higher installations of DaVinci Resolve. Turning this checkbox on lets DaVinci Resolve display 10-bit images in the Viewer."

I see the same issue with 10 bit viewer option and also without the 10 bit viewer option.
The colour picker gets the luminance wrong on a simple monochrome colour generator. The colour I set the generator to is sampled incorrectly when applied to another instance of the same colour generator.

Thanks for the screen shot Jack. Unfortunately the problem persists even with that check on.
