Also known as: Tailwind sky-500

oklch(0.69203 0.15955 240.379) → #00A6F4

Values are shown at full precision, so converting back gives exactly #00a6f4. 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(0.69203 0.15955 240.379)
```

2. OKLCH → Oklab

a = C·cos H = -0.07886
b = C·sin H = -0.13870

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.630843
m′ = L − 0.1056·a − 0.0639·b = 0.709211
s′ = L − 0.0895·a − 1.2915·b = 0.878214

4. cube

l = 0.630843³ = 0.251052
m = 0.709211³ = 0.356719
s = 0.878214³ = 0.677332

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = -0.000004
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.381319
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.904646

6. linear → sRGB, × 255

R = 0.00000 × 255 = 0.00 → 0
G = 0.65098 × 255 = 166.00 → 166
B = 0.95686 × 255 = 244.00 → 244

7. RGB → HEX
```
#00A6F4
