HEX to OKLCH: #696969

Result

Values are shown at full precision, so converting back gives exactly #696969. 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: 105/255 = 0.41176 → 0.141263  (((x + 0.055) / 1.055)^2.4)
   G: 105/255 = 0.41176 → 0.141263  (((x + 0.055) / 1.055)^2.4)
   B: 105/255 = 0.41176 → 0.141263  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.141263
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.141263
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.141263

3. 3. cube root

   l′ = ∛0.141263 = 0.520807
   m′ = ∛0.141263 = 0.520807
   s′ = ∛0.141263 = 0.520807

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.52081
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.00000
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.00000

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.00000
   H: a and b are ~0, so the hue is undefined (written as 0)
   L = 0.52081

6. 6. OKLCH

   oklch(0.52081 0.00000 0.000)
   rounded: oklch(0.521 0.000 0.0)
