Here s a simple function that creates a CSS color string from RGB values ranging from 0 to 255   function rgb r  g  b     return  rgb   r     g     b          Alternatively  to create fewer string objects   you could use array join     function rgb r  g  b     return   rgb   r     g     b      join          The above functions will only work properly if  r  g  and b  are integers between 0 and 255  If they are not integers  the color system will treat them as in the range from 0 to 1  To account for non-integer numbers  use the following   function rgb r  g  b     r   Math floor r     g   Math floor g     b   Math floor b     return   rgb   r     g     b      join          You could also use ES6 language features   const rgb    r  g  b    gt      rgb   Math floor r     Math floor g     Math floor b
