OKLCH to HEX: #94A3B8

Result

Values are shown at full precision, so converting back gives exactly #94a3b8. 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(0.71067 0.03511 256.788)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.00802
   b = C·sin H = -0.03418

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.700113
   m′ = L − 0.1056·a − 0.0639·b = 0.713700
   s′ = L − 0.0895·a − 1.2915·b = 0.755532

4. 4. cube

   l = 0.700113³ = 0.343166
   m = 0.713700³ = 0.363535
   s = 0.755532³ = 0.431279

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.296144
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.366249
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.479301

6. 6. linear → sRGB, × 255

   R = 0.58040 × 255 = 148.00 → 148
   G = 0.63921 × 255 = 163.00 → 163
   B = 0.72156 × 255 = 184.00 → 184
