What are RGB colour channels?

Every pixel in a colour image is composed of three channels: Red, Green, and Blue. By adjusting each channel independently, you can shift the overall colour tone of the image -- increasing the red channel makes the image warmer, while increasing blue makes it cooler.

How is adjusting colour channels different from adjusting HSL?

Colour channel adjustment directly multiplies or offsets the R, G, and B values per pixel, giving low-level control. HSL (Hue, Saturation, Lightness) operates in a perceptual colour space and is generally more intuitive for artistic adjustments.

Will channel adjustments affect image quality?

The adjustments are non-destructive during editing. Final quality depends on the output format chosen -- saving as PNG preserves all data losslessly, while JPEG applies compression.
