Color grading tools for photographers and colorists

See your photo on every film stock at once — Portra-, Ektar-, Vision3- and Eterna-inspired negatives, scanned or printed.

Drag to wipe between the original and a graded version of your own photo, with six cinematic looks built in.

Pull the dominant palette out of a film still, see the hues on the colour wheel, and find out whether the look is complementary, analogous, or triadic.

RGB histogram, luma histogram, waveform, and parade for any image, with clipping measured for you.

Drag temperature and tint to remove a colour cast, and see the exact channel gains behind the correction.

Learn the three primary correction controls by dragging them against a live curve, grey ramp, and image.

Compare delivery colour spaces on a chromaticity diagram, plus a plain guide to SDR, HDR, PQ, and HLG.

Find the right Kelvin value for any light source. Interactive chart from candlelight to open shade.

Choose shadow and highlight colors and preview the split-tone effect before applying it to your images.

Upload a graded image and the .cube that was applied to it, and recover the ungraded original.

Visualise how blending a LUT at different strength values affects your image before committing.

See how LUT opacity changes the look of a grade from 0% to 100%, and find the right blend point.

S-Log2, S-Log3, C-Log, N-Log, D-Log — find the right technical LUT or transform for your camera's log profile.

Lab and RGB reference values for accurate skin tone grading across a wide range of complexions.

Select your camera and get a recommended LUT and grading workflow tailored to its colour science.

Grade a ColorChecker, upload it, and measure the CIEDE2000 ΔE of all 24 patches against X-Rite reference values.

A 24-patch colour reference generated from official X-Rite Lab D50 values. Verify LUTs and test colour accuracy.

An 18% reflectance grey card and 11-step neutral wedge at exact sRGB values. Set exposure and spot colour casts.
