OKLCH to HEX: #FFFAFA

Result

Values are shown at full precision, so converting back gives exactly #fffafa. 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(0.98894 0.00534 17.247)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.00510
   b = C·sin H = 0.00158

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.991303
   m′ = L − 0.1056·a − 0.0639·b = 0.988301
   s′ = L − 0.0895·a − 1.2915·b = 0.986439

4. 4. cube

   l = 0.991303³ = 0.974135
   m = 0.988301³ = 0.965311
   s = 0.986439³ = 0.959866

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 1.000028
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.955976
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.955976

6. 6. linear → sRGB, × 255

   R = 1.00000 × 255 = 255.00 → 255
   G = 0.98039 × 255 = 250.00 → 250
   B = 0.98039 × 255 = 250.00 → 250

7. 7. RGB → HEX
