HEX to OKLCH: #FFFFF0

Result

Values are shown at full precision, so converting back gives exactly #fffff0. 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: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
   G: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
   B: 240/255 = 0.94118 → 0.871367  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.993382
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.986185
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.918964

3. 3. cube root

   l′ = ∛0.993382 = 0.997789
   m′ = ∛0.986185 = 0.995374
   s′ = ∛0.918964 = 0.972224

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.99598
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.00565
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.01878

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.01962
   H = atan2(b, a) = 106.751°
   L = 0.99598

6. 6. OKLCH

   oklch(0.99598 0.01962 106.751)
   rounded: oklch(0.996 0.020 106.8)
