Question 66
Many computer applications, such as those for word-processing and slide-making, have colour options. In the ‘more colours’ options of these there are RGB tools to customise colours.
The letters RGB stand for ‘red’, ‘green’ and ‘blue’, the primary colours of light. You can adjust these to make whatever colour you want. For example, bright red has:
- R at maximum
- G at zero
- B at zero.
Bright yellow has:
- R at maximum
- G at maximum
- B at zero.
Try making:
- magenta
- cyan
- white
- black.
Now make some other colours of your choice.
In each case, write down the RGB settings for each colour.
