How it works
Click on white — done
Find anything in your photo that should be pure white or neutral grey — a white wall, shirt, paper, teeth. Click it. The tool reads those RGB values and calculates exactly how much to shift red, green and blue to neutralize the cast.
What causes color casts?
Indoor bulbs add yellow/orange. Fluorescent lights add green. Shade and overcast skies add blue. Your camera guesses the light source — when it guesses wrong, the whole photo shifts. This tool reverses that shift.
Temperature & Tint sliders
Temperature moves between cool blue and warm yellow. Tint moves between green and magenta. These match how every professional photo editor (Lightroom, Capture One) controls white balance.
