8 digit hex rgba value

I am working with a piece of code that requires me to use 8 digit hex rgba values

-b [ --background-color ] arg (=efefefff) color of background in hex rgba
-f [ --foreground-color ] arg (=00000000) color of background in hex rgba

I cant for the life of me figure out what the 8 digit combination for black is

00000000

is completely transparent not black

can some help?

Solution

  • Black has no red, green or blue, but it is not transparent, so the alpha needs to be ff. Therefore the combination you seek is

    000000ff
