Questions and answers
Before you trust the result: what to know about the format, the limits, your data and the tools next to it.
Write each channel, 0 to 255, as two base-16 digits: 59 is 3 × 16 + 11, so 3b; 130 is 8 × 16 + 2, so 82; 246 is 15 × 16 + 6, so f6. Put them together after a # and rgb(59 130 246) is #3b82f6.
As a fourth pair: an alpha of 0.5 is 128 of 255, which is 80 in hex, so rgba(59, 130, 246, 0.5) is #3b82f680. Every current browser reads 8-digit hex.
Lowercase, as Tailwind and most style guides write it; CSS doesn't care, #3B82F6 and #3b82f6 are the same color.
rgb(59 130 246), rgb(59, 130, 246), rgba() with alpha, percentages like rgb(23% 51% 96%), or just the three numbers: 59, 130, 246. Values above 255 are clamped, as CSS does.
