OKLCH to HEX: #22D3EE

Also known as: Tailwind v3 cyan-400

oklch(0.79712 0.13389 211.530) → #22D3EE

Values are shown at full precision, so converting back gives exactly #22d3ee. 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. input
```
oklch(0.79712 0.13389 211.530)
```

2. OKLCH → Oklab

a = C·cos H = -0.11412
b = C·sin H = -0.07002

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.736779
m′ = L − 0.1056·a − 0.0639·b = 0.813638
s′ = L − 0.0895·a − 1.2915·b = 0.897758

4. cube

l = 0.736779³ = 0.399955
m = 0.813638³ = 0.538634
s = 0.897758³ = 0.723566

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.015990
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.651418
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.855009

6. linear → sRGB, × 255

R = 0.13330 × 255 = 33.99 → 34
G = 0.82746 × 255 = 211.00 → 211
B = 0.93334 × 255 = 238.00 → 238

7. RGB → HEX
```
#22D3EE
```
