Comparing brush strokes in linear gamma and perceptually uniform sRGB color spaces. Upcoming articles will examine channel mixing, converting a color image to black and white, applying curves, and using different blend modes.Ībove right: Krita brush strokes, regular sRGB color space.

This article is the first of a planned series of articles on editing in a linear gamma color space. This article compares blurring and normal mode blending of colors in a linear gamma version of the sRGB color space to blurring/blending the same colors using the regular (approximately gamma=2.2) sRGB color space. If it's not easy, is it worth the hassle?.Linear and regular gamma: technically correct vs "prettier".Final thoughts on blurring and normal mode blending in a linear gamma RGB color space.State Fair corn dog stand: regular sRGB turned silver hair to yellow and a turquoise shirt to green.Flowers: regular sRGB turned a blue sky into a mottled green sky.Saturation vs brightness: which contributes most to the darkening artifacts that result when improperly mixing colors?.Roughly 50% bright, 50% saturated colors: darkening is visible but not especially noticeable.
Roughly 75% bright, 75% saturated colors: darkening is lessened, but is still obvious.100% bright, 100% saturated colors: very noticeable darkening artifacts.Blurring and Normal Mode Blending: linear gamma and regular sRGB compared.Introduction: Editing in linear gamma color spaces.
