HEX to OKLCH: #FDF4FF

Result

Values are shown at full precision, so converting back gives exactly #fdf4ff. 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: 253/255 = 0.99216 → 0.982251  (((x + 0.055) / 1.055)^2.4)
   G: 244/255 = 0.95686 → 0.904661  (((x + 0.055) / 1.055)^2.4)
   B: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.941550
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.931342
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.971574

3. 3. cube root

   l′ = ∛0.941550 = 0.980124
   m′ = ∛0.931342 = 0.976569
   s′ = ∛0.971574 = 0.990433

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.97726
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.01328
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.01112

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.01732
   H = atan2(b, a) = 320.058°
   L = 0.97726

6. 6. OKLCH

   oklch(0.97726 0.01732 320.058)
   rounded: oklch(0.977 0.017 320.1)
