Hi, I am not well up on colour but have dabbled with NSColor in Cocoa.
There are numerous methods for creating an NSColor: Creating an NSColor Object from Component Values + colorWithCalibratedHue:saturation:brightness:alpha: + colorWithCalibratedRed:green:blue:alpha: + colorWithCalibratedWhite:alpha: + colorWithCatalogName:colorName: + colorWithDeviceCyan:magenta:yellow:black:alpha: + colorWithDeviceHue:saturation:brightness:alpha: + colorWithDeviceRed:green:blue:alpha: + colorWithDeviceWhite:alpha: + colorWithCIColor: + colorWithColorSpace:components:count: + colorWithSRGBRed:green:blue:alpha: + colorWithGenericGamma22White:alpha: + colorWithHue:saturation:brightness:alpha: + colorWithRed:green:blue:alpha: + colorWithWhite:alpha: Could it be that LiveCode is using the incorrect method of determining/obtaining the colour. If you wish to read up on NSColor follow this link: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSColor_Class/Reference/Reference.html All the best and good luck.
