The color picker tool within Adobe Photoshop displays the hexadecimal,
RGB, and HSL color values
RGB & RGBa Colors
RGB color values are stated using the
rgb()
function, which stands for red, green, and
blue. The function accepts three comma-separated values, each of which is an integer from
0
to
255
. A value of
0
would be pure black; a value of
255
would be pure white.
As we might expect, the first value within the
rgb()
function represents the red channel,
the second value represents the green channel, and the third value represents the blue chan-
nel.
If we were to recreate the shade of orange from before as an RGB color value, it would be
represented as
rgb(255, 102, 0)
.
Also, using the same maroon and yellow background colors from before, we could replace
the keyword or hexadecimal color values with RGB color values.
