OKLCH to HEX: #D1D5DB

Result

Values are shown at full precision, so converting back gives exactly #d1d5db. 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(0.87168 0.00934 258.338)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.00189
   b = C·sin H = -0.00915

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.868958
   m′ = L − 0.1056·a − 0.0639·b = 0.872463
   s′ = L − 0.0895·a − 1.2915·b = 0.883662

4. 4. cube

   l = 0.868958³ = 0.656139
   m = 0.872463³ = 0.664112
   s = 0.883662³ = 0.690016

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.637590
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.665385
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.708379

6. 6. linear → sRGB, × 255

   R = 0.81960 × 255 = 209.00 → 209
   G = 0.83529 × 255 = 213.00 → 213
   B = 0.85883 × 255 = 219.00 → 219

7. 7. RGB → HEX
