Color changes with PNG export.

[David Rosnick]

On the left, we have the graph I actually want (ignore please the slight transparency difference between legend and data colors). On the right, we have the PNG output from

graph export XXXX.png, replace

run immediately after the production of the graph. I tried

set printcolor asis

but this had no effect. I have had no problem producing PNG files with these colors previously. I have also tried exporting to PDF, getting different colors again than either of these.
