/correct-color

Color calibration against a ColorChecker chart that's already been shot into a Premiere Pro sequence: extracts the frame containing the chart, fits a correction LUT from it (calibrate-lut), selects the target clip, and loads the fitted .cube onto that clip's Lumetri Color Input LUT by driving the native Premiere UI. Use this when the chart is on the timeline already; if you just have a standalone chart photo, go straight to the calibrate-lut skill instead.
