Also known as: Tailwind teal-900

oklch(0.38711 0.06341 187.211) → #0B4F4A

Values are shown at full precision, so converting back gives exactly #0b4f4a. 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(0.38711 0.06341 187.211)
```

2. OKLCH → Oklab

a = C·cos H = -0.06291
b = C·sin H = -0.00796

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.360459
m′ = L − 0.1056·a − 0.0639·b = 0.394259
s′ = L − 0.0895·a − 1.2915·b = 0.403019

4. cube

l = 0.360459³ = 0.046835
m = 0.394259³ = 0.061284
s = 0.403019³ = 0.065460

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.003344
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.078186
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.068476

6. linear → sRGB, × 255

R = 0.04311 × 255 = 10.99 → 11
G = 0.30980 × 255 = 79.00 → 79
B = 0.29019 × 255 = 74.00 → 74

7. RGB → HEX
```
#0B4F4A
