OKLCH to HEX: #00BFFF

Result

Values are shown at full precision, so converting back gives exactly #00bfff. 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(0.75535 0.15342 231.639)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.09521
   b = C·sin H = -0.12030

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.691652
   m′ = L − 0.1056·a − 0.0639·b = 0.773083
   s′ = L − 0.0895·a − 1.2915·b = 0.919235

4. 4. cube

   l = 0.691652³ = 0.330874
   m = 0.773083³ = 0.462038
   s = 0.919235³ = 0.776746

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.000005
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.520995
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.999989

6. 6. linear → sRGB, × 255

   R = 0.00006 × 255 = 0.01 → 0
   G = 0.74902 × 255 = 191.00 → 191
   B = 1.00000 × 255 = 255.00 → 255
