HEX to OKLCH: #DDD6FE

Result

Values are shown at full precision, so converting back gives exactly #ddd6fe. 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: 221/255 = 0.86667 → 0.723055  (((x + 0.055) / 1.055)^2.4)
   G: 214/255 = 0.83922 → 0.672443  (((x + 0.055) / 1.055)^2.4)
   B: 254/255 = 0.99608 → 0.991102  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.709700
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.717391
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.877661

3. 3. cube root

   l′ = ∛0.709700 = 0.891987
   m′ = ∛0.717391 = 0.895197
   s′ = ∛0.877661 = 0.957434

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.89427
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.02169
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.05041

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.05488
   H = atan2(b, a) = 293.283°
   L = 0.89427

6. 6. OKLCH

   oklch(0.89427 0.05488 293.283)
   rounded: oklch(0.894 0.055 293.3)
