OKLCH to HEX: #C71585

Result

Values are shown at full precision, so converting back gives exactly #c71585. The rounded form is what you normally paste into CSS.

Step-by-step math

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

1. 1. input

   oklch(0.55337 0.22165 349.687)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.21807
   b = C·sin H = -0.03968

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.631236
   m′ = L − 0.1056·a − 0.0639·b = 0.532884
   s′ = L − 0.0895·a − 1.2915·b = 0.585104

4. 4. cube

   l = 0.631236³ = 0.251521
   m = 0.532884³ = 0.151321
   s = 0.585104³ = 0.200308

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.571127
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.007502
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.234552

6. 6. linear → sRGB, × 255

   R = 0.78039 × 255 = 199.00 → 199
   G = 0.08238 × 255 = 21.01 → 21
   B = 0.52157 × 255 = 133.00 → 133

7. 7. RGB → HEX
