Frequently asked questions
How do I convert RGB to hex manually?
Convert each 0–255 value to two hex digits and join them: rgb(37, 99, 235) → 25, 63, EB → #2563EB.
How is alpha converted?
rgba(37, 99, 235, 0.5) becomes the 8-digit #2563eb80 – the alpha (0–1) is multiplied by 255 and appended as the last two digits.
Are hex codes case-sensitive?
No. #2563EB and #2563eb are the same colour in CSS, SVG and design tools.
