RGB and RGBA 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).
RGBA (rgba(r, g, b, a)) is RGB plus an alpha channel from 0 (fully transparent) to 1 (solid), for example rgba(255, 87, 51, 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.
