OKLCH to HEX: #FDE047

Result

Values are shown at full precision, so converting back gives exactly #fde047. 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(0.90524 0.16568 98.111)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.02338
   b = C·sin H = 0.16402

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.931372
   m′ = L − 0.1056·a − 0.0639·b = 0.897234
   s′ = L − 0.0895·a − 1.2915·b = 0.695499

4. 4. cube

   l = 0.931372³ = 0.807922
   m = 0.897234³ = 0.722299
   s = 0.695499³ = 0.336426

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.982235
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.745399
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.063017

6. 6. linear → sRGB, × 255

   R = 0.99215 × 255 = 253.00 → 253
   G = 0.87843 × 255 = 224.00 → 224
   B = 0.27845 × 255 = 71.00 → 71

7. 7. RGB → HEX
