HEX to OKLCH: #F0FDFA

Result

Values are shown at full precision, so converting back gives exactly #f0fdfa. 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: 253/255 = 0.99216 → 0.982251  (((x + 0.055) / 1.055)^2.4)
   B: 250/255 = 0.98039 → 0.955973  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.935190
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.955932
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.955905

3. 3. cube root

   l′ = ∛0.935190 = 0.977912
   m′ = ∛0.955932 = 0.985089
   s′ = ∛0.955905 = 0.985080

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.98358
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.01420
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00018

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.01420
   H = atan2(b, a) = 180.720°
   L = 0.98358

6. 6. OKLCH

   oklch(0.98358 0.01420 180.720)
   rounded: oklch(0.984 0.014 180.7)
