Link to the challenge:

You haven’t explained what you need help with exactly, but try changing:

  .blue-text {
    color: RGB(0, 0, 255)


  .blue-text {
    color: rgb(0, 0, 255)

and add a semicolon to the end of the color: rgb(...); lines

its telling me to use rgb for the colours? what do they mean

So rgb stands for Red, Green, Blue values, the three primary colors that make up every other color. Their values range from 0 up to 255 for each. So rgb(255,0,0) is 255 worth of red, for lack of a better way to explain, 0 of green, and 0 of blue. So the color will be Bright Red. CSS accepts color name such as “red” and also rgb values, which are formatted as (red#, green#, blue#) (and also HEX#s but you’ll get to there later).
