HEX to OKLCH: #FECDD3

Result

Values are shown at full precision, so converting back gives exactly #fecdd3. 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: 254/255 = 0.99608 → 0.991102  (((x + 0.055) / 1.055)^2.4)
   G: 205/255 = 0.80392 → 0.610496  (((x + 0.055) / 1.055)^2.4)
   B: 211/255 = 0.82745 → 0.651406  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.769494
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.695541
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.669877

3. 3. cube root

   l′ = ∛0.769494 = 0.916365
   m′ = ∛0.695541 = 0.886015
   s′ = ∛0.669877 = 0.874980

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.89245
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.05506
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.00971

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.05591
   H = atan2(b, a) = 10.001°
   L = 0.89245

6. 6. OKLCH

   oklch(0.89245 0.05591 10.001)
   rounded: oklch(0.892 0.056 10.0)
