HEX to OKLCH: #D4D4D8

Result

Values are shown at full precision, so converting back gives exactly #d4d4d8. 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. sRGB → linear

   R: 212/255 = 0.83137 → 0.658375  (((x + 0.055) / 1.055)^2.4)
   G: 212/255 = 0.83137 → 0.658375  (((x + 0.055) / 1.055)^2.4)
   B: 216/255 = 0.84706 → 0.686685  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.659831
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.661415
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.676210

3. 3. cube root

   l′ = ∛0.659831 = 0.870585
   m′ = ∛0.661415 = 0.871281
   s′ = ∛0.676210 = 0.877729

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.87111
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.00153
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00523

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.00545
   H = atan2(b, a) = 286.286°
   L = 0.87111

6. 6. OKLCH

   oklch(0.87111 0.00545 286.286)
   rounded: oklch(0.871 0.005 286.3)
