Description Thomas Singer CLA 2022-03-07 07:06:42 EST 
Please launch the attached snippet. It will show 2 tabs within a TabFolder and prints the background mode as well as the background color of the TabFolder and the contained Composite. The output on MacOS 10.14 is:

tabFolder.getBackgroundMode() = 0
tabFolder.getBackground() = Color {236, 236, 236, 255}
composite.getBackground() = Color {236, 236, 236, 255}

but when verifying with "/Applications/Utilities/Digital Colour Meter" the color actually is (227, 227, 227).
