Overview
The most mechanical color adjustment, directly adding to or subtracting from R/G/B values. Use it for tinting—such as making the entire image slightly bluer by adding or removing a color cast—and for technical work that requires precise channel values.
Usage tips
- The shortest route to an ambient tint is blue +0.05–0.1 for night, more red for evening, or more green for a poisonous swamp. It is a quick broad stroke for establishing atmosphere.
- Natural-looking lightness, chroma, or hue adjustments are the domain of
oklch_adjust/hsv_adjust. Because this node adds values, highlights saturate first. - For precise processing of only one channel, such as preparing mask material, also
consider combining it with
channel_split/channel_merge.
Common pitfalls
- Only bright areas do not change color: addition saturates at 1.0, and adding
anything to white leaves it white. To apply a tint, you can instead combine colors
with
blend(Multiply/Screen).
