I've finally almost finished my course in interior design studies, so I though I might as well node my homework for the final exam. One topic was the 7 basic colour schemes, not to be confused with the 8 colour contrasts. These schemes are based on the colour wheel, which is a circle with 12 colours in this case.

         yellow
     YO         YG
  orange          green
OR                   BG
  red              blue
     RP         BP
         purple

- Monochromatic: one colour, but used in different tints, shades and materials (a light blue stainless steel chair gives another impression than a fluffy dark blue chaise lounge so it's not neccesarily boring).
- Complementary: two colours opposite in the colour wheel are combined. Red with green, blue with orange etc. Normally one colour dominates the scheme.
- Analogous: 2 or 3 colours adjacent in the wheel. E.g. green, blue-green (BG) and blue.
- Split complementary: one hue (pure colour) + two hues on either side of the complementary hue. Purple with yellow-orange (YO) and yellow-green (YG).
- Triad or triadic: three hues equidistant around the circle. Like orange, green and purple. This may not sound very compelling to you, but especially children tend to like those fresh combinations.
- Double complementary: is based upon two pairs of complementary hues. This combination, like OR+red+BG+green is often used, because it is a safe and balanced combination.
- Tetrad: is like triad, but then based on 4 hues at equidistance in the colour wheel. This combination is considered as the one most difficult to combine.

Ah well, designers may talk in vague blahblah terms, but that's what every industry branch does. After all, when you keep things unclear you have an advantage that the client thinks s/he really needs you to get something done very well.
