  3. Primaries
    The idea is, with three primaries, you can mix all the
    colours.
    —Red
    —Blue
    —Yellow

  5. Secondaries
    —Purple = red + blue
    —Green = blue + yellow
    —Orange = yellow + red
    These, with the primaries, form the basics of a
    colour wheel

  6. Complementary colours
    —Make each other stand out
    —Can be used to mix greys

  7. Hue, Saturation, Brightness
    —Saturation = intensity of a colour
    —Brightness = tone of a colour
    —Hue = the colour family

  8. Mixing
    Things to consider
    —How saturated do you want the colour to be?
    —How light or dark? (what is the value?)
    —What’s the undertone of your palette?

  9. Saturation
    —All colours together = “black”
    —To desaturate your colour (turn it slightly grey),
    mix a bit of every primary (or its complementary)
    —Because the primaries can have undertones it can
    determine the saturation of your secondaries
    You can’t get more saturated than your primaries

  10. Value / tone / brightness
    —White++ = chalkier/pastel colours
    —Black++ = darker/richer colours

  11. Contrast
    —Things only look light because there’s dark
    —Things only look vivid, because there’s dull
    You can still have very rich colours that are
    technically “desaturated”
