Subject: Suggested color schemes for points, not regions?
I have seen a couple of posts about color schemes like those at the
ColorBrewer site. Most recently:
http://geography.uoregon.edu/datagraphics/color_scales.htm
These color schemes can work very well for regions (bars, polygons,
images, etc.) but are not very suitable for points and/or lines.
Is anyone aware of research/suggestions for a color scheme to use for
scatter plots? I've looked at great length and have found little on this
topic.
My current scheme of choice is a set of fairly saturated colors along the
lines of:
navy
brown/orange
black
purple
red
medium green
This is similar to the 'paired' color scheme, but using only the saturated
colors and substituting black for yellow. Depending on circumstances, I
sometimes use a different glyph for each color. The hard part about all
this is to make sure that each color/glyph combination has the same
'attention-getting' power.
Any discussion or comments are welcome.
