HEX to OKLCH: #F5FFFA

Result

Values are shown at full precision, so converting back gives exactly #f5fffa. 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: 245/255 = 0.96078 → 0.913099  (((x + 0.055) / 1.055)^2.4)
   G: 255/255 = 1.00000 → 1.000000  (((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 = 0.961912
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.976857
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.964591

3. 3. cube root

   l′ = ∛0.961912 = 0.987139
   m′ = ∛0.976857 = 0.992225
   s′ = ∛0.964591 = 0.988055

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.99117
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.01194
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.00324

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.01237
   H = atan2(b, a) = 164.813°
   L = 0.99117

6. 6. OKLCH

   oklch(0.99117 0.01237 164.813)
   rounded: oklch(0.991 0.012 164.8)
