.. the percentage part of r.colors seems to be the culprit:


r.info:
Data Type:    DCELL
Range of data:    min =  177.700000 max = 177.700000


r.colors col=rules
Enter rules, "end" when done, "help" if you need it.
fp: Data range is 177.6999999999999886313162278 to 177.6999999999999886313162278
> 0% red
> 100% red
> end


If I set the rules to
> 170 red
> 180 red
> end

it displays fine.
