HEX to OKLCH: #E3E7E8

Result

Values are shown at full precision, so converting back gives exactly #e3e7e8. 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: 227/255 = 0.89020 → 0.768151  (((x + 0.055) / 1.055)^2.4)
   G: 231/255 = 0.90588 → 0.799103  (((x + 0.055) / 1.055)^2.4)
   B: 232/255 = 0.90980 → 0.806952  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.786748
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.793387
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.801315

3. 3. cube root

   l′ = ∛0.786748 = 0.923163
   m′ = ∛0.793387 = 0.925753
   s′ = ∛0.801315 = 0.928826

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.92520
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.00374
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00255

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.00453
   H = atan2(b, a) = 214.330°
   L = 0.92520

6. 6. OKLCH

   oklch(0.92520 0.00453 214.330)
   rounded: oklch(0.925 0.005 214.3)
