SASS: converting RGB to RGBa

Question

I have set up the colours of my project like so:

$blue: rgb(75, 179, 209);

Is there any way to use this variable and convert the value into RGBa elsewhere as needed?

Answer 1

using rgba instance method

you can

$blue: rgb(75, 179, 209);

body {
    background:rgba($blue, .5);
}
