The blocks below are labelled for the true color they contain.
If the colors do not appear to be correctly labelled, there
may be one or more of several causes:
The room lighting may be unusual.
People's eyes have different abilities to perceive different
colors--these differences are even noted between the right and
left eyes of one person. This does not mean you are color blind,
but it could affect how you are seeing these color blocks.
Your monitor may need to be adjusted. You can adjust the
contrast and brightness controls on your monitor control panel
or check your User's Manual for more advanced adjustments.
