Balance image color by shifting the red, green, and blue channels. Positive values add that channel. Negative values remove it. The adjustment applies to the whole image.
RGB channel shifts
Use small moves first. Most cast corrections sit inside -25 to +25 per channel.
- Add Red or reduce Blue when a photo looks too cold.
- Add Blue or reduce Red and Green when a photo looks too yellow.
- Reduce Green when indoor lighting looks fluorescent.
- Add Green or reduce Red and Blue when shadows look magenta.
The sliders run from -100 to +100. Large values are better for stylized color grades than for natural correction.
White balance and color casts
RGB balance can fix many white balance problems, but it is not the same as a camera-style temperature and tint model. It changes channels directly, so the result can move faster and more abruptly.
For a blue cast, try Red +8 to +20, Green +3 to +12, and Blue -10 to -30.
For a yellow cast, try Red -8 to -25, Green -5 to -18, and Blue +5 to +18.
For a green cast, try Green -10 to -30, Red +5 to +15, and Blue 0 to +10.
Skin tones and product photos
Skin tones often break when Blue is reduced too far. Use smaller Blue reductions and add a little Red instead. Product photos with white backgrounds should be checked against the background first, because a channel shift that fixes the product can tint the white area.
If the image becomes flat after color correction, use brightness and contrast after the color balance step.
How the pixels change
For each pixel, the editor applies:
R = clamp(R + redShift)G = clamp(G + greenShift)B = clamp(B + blueShift)
Values are clamped to 0-255, and alpha is preserved. Preview uses a capped size for responsiveness; download renders the full image dimensions.
