OKLCH to HEX: #E4E4E7

Result

Values are shown at full precision, so converting back gives exactly #e4e4e7. 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(0.91973 0.00403 286.320)

2. 2. OKLCH → Oklab

   a = C·cos H = 0.00113
   b = C·sin H = -0.00387

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.919344
   m′ = L − 0.1056·a − 0.0639·b = 0.919857
   s′ = L − 0.0895·a − 1.2915·b = 0.924624

4. 4. cube

   l = 0.919344³ = 0.777024
   m = 0.919857³ = 0.778326
   s = 0.924624³ = 0.790487

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.775827
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.775827
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.799099

6. 6. linear → sRGB, × 255

   R = 0.89412 × 255 = 228.00 → 228
   G = 0.89412 × 255 = 228.00 → 228
   B = 0.90588 × 255 = 231.00 → 231

7. 7. RGB → HEX
