Step-by-step math

Every number below is computed from the input, nothing is looked up.

  1. 1. input

    H = 9.13°, S = 100.00%, L = 63.92%
  2. 2. C

    C = (1 − |2L − 1|) × S = 0.72160
  3. 3. X

    X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.10980   (H / 60° = 0.1522, sector 0)
  4. 4. m

    m = L − C / 2 = 0.27840
  5. 5. (R′, G′, B′) + m

    (R′, G′, B′) = (0.72160, 0.10980, 0.00000)
    R = round((0.72160 + 0.27840) × 255) = 255
    G = round((0.10980 + 0.27840) × 255) = 99
    B = round((0.00000 + 0.27840) × 255) = 71
  6. 6. RGB → HEX
