Also known as: Tailwind green-600

oklch(0.63198 0.18597 147.369) → #00A63E

Values are shown at full precision, so converting back gives exactly #00a63e. 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(0.63198 0.18597 147.369)
```

2. OKLCH → Oklab

a = C·cos H = -0.15662
b = C·sin H = 0.10028

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.591548
m′ = L − 0.1056·a − 0.0639·b = 0.642109
s′ = L − 0.0895·a − 1.2915·b = 0.516485

4. cube

l = 0.591548³ = 0.207000
m = 0.642109³ = 0.264745
s = 0.516485³ = 0.137776

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.000007
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.381328
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.048173

6. linear → sRGB, × 255

R = 0.00009 × 255 = 0.02 → 0
G = 0.65098 × 255 = 166.00 → 166
B = 0.24314 × 255 = 62.00 → 62

7. RGB → HEX
```
#00A63E
```
