HEX to OKLCH: #DFF2FE

Result

Values are shown at full precision, so converting back gives exactly #dff2fe. 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: 223/255 = 0.87451 → 0.737910  (((x + 0.055) / 1.055)^2.4)
   G: 242/255 = 0.94902 → 0.887923  (((x + 0.055) / 1.055)^2.4)
   B: 254/255 = 0.99608 → 0.991102  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.831393
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.867216
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.939677

3. 3. cube root

   l′ = ∛0.831393 = 0.940305
   m′ = ∛0.867216 = 0.953621
   s′ = ∛0.939677 = 0.979474

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.95071
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.01469
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.02125

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.02583
   H = atan2(b, a) = 235.347°
   L = 0.95071

6. 6. OKLCH

   oklch(0.95071 0.02583 235.347)
   rounded: oklch(0.951 0.026 235.3)
