RGB and HSLA colour formats explained
RGB (rgb(r, g, b)) describes a colour by mixing red, green and blue light, each from 0 to 255, for example rgb(255, 87, 51).
HSLA (hsla(h, s%, l%, a)) is HSL with an added alpha (transparency) value, for example hsla(11, 100%, 60%, 0.5).
Both formats can describe the same colour on screen — they are just different ways of writing it. Different tools and code libraries prefer different formats, which is why converting is so useful.
