HEX to OKLCH: #A2F4FD

Also known as: Tailwind cyan-200

#A2F4FD → oklch(0.918 0.081 204.6)

Values are shown at full precision, so converting back gives exactly #a2f4fd. 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: 162/255 = 0.63529 → 0.361307  (((x + 0.055) / 1.055)^2.4)
G: 244/255 = 0.95686 → 0.904661  (((x + 0.055) / 1.055)^2.4)
B: 253/255 = 0.99216 → 0.982251  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.684670
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.797855
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.905561

3. cube root

l′ = ∛0.684670 = 0.881375
m′ = ∛0.797855 = 0.927487
s′ = ∛0.905561 = 0.967474

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.91762
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.07319
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.03353

5. Oklab → OKLCH

C = √(a² + b²) = 0.08051
H = atan2(b, a) = 204.613°
L = 0.91762

6. OKLCH

oklch(0.91762 0.08051 204.613)
rounded: oklch(0.918 0.081 204.6)
