Quick HCT uses a precomputed tonal map to quickly approximate transformations of RGB colors to a given tonal value. Tone is one of the dimensions of the HCT color space introduced by Material Design 3. A tone value of 100 is equivalent to the idea of light at its maximum and results in white. Every tone value between 0 and 100 expresses the amount of light present in the color.
