HEX to OKLCH: #EEF2FF

Result

Values are shown at full precision, so converting back gives exactly #eef2ff. 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: 238/255 = 0.93333 → 0.854993  (((x + 0.055) / 1.055)^2.4)
   G: 242/255 = 0.94902 → 0.887923  (((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 = 0.880114
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.892982
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.955621

3. 3. cube root

   l′ = ∛0.880114 = 0.958325
   m′ = ∛0.892982 = 0.962973
   s′ = ∛0.955621 = 0.984983

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.96191
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.00072
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.01792

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.01793
   H = atan2(b, a) = 272.314°
   L = 0.96191

6. 6. OKLCH

   oklch(0.96191 0.01793 272.314)
   rounded: oklch(0.962 0.018 272.3)
