Values are shown at full precision, so converting back gives exactly #ffdab9. 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. sRGB → linear

R: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
G: 218/255 = 0.85490 → 0.701102  (((x + 0.055) / 1.055)^2.4)
B: 185/255 = 0.72549 → 0.485150  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.813204
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.741247
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.591450

3. cube root

l′ = ∛0.813204 = 0.933397
m′ = ∛0.741247 = 0.905012
s′ = ∛0.591450 = 0.839407

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.91125
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.02659
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.05379

5. Oklab → OKLCH

C = √(a² + b²) = 0.06000
H = atan2(b, a) = 63.699°
L = 0.91125

6. OKLCH

oklch(0.91125 0.06000 63.699)
rounded: oklch(0.911 0.060 63.7)
