HEX to OKLCH: #F0FFF0

Result

Values are shown at full precision, so converting back gives exactly #f0fff0. 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: 240/255 = 0.94118 → 0.871367  (((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 = 0.940357
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.958927
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.907605

3. 3. cube root

   l′ = ∛0.940357 = 0.979710
   m′ = ∛0.958927 = 0.986117
   s′ = ∛0.907605 = 0.968201

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.98484
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.02075
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.01432

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.02521
   H = atan2(b, a) = 145.381°
   L = 0.98484

6. 6. OKLCH

   oklch(0.98484 0.02521 145.381)
   rounded: oklch(0.985 0.025 145.4)
