I also think this is a neat function. I might suggest adding a stop error
for dislexics like me. Something like 
if(length(qx.colors)==0) stop(paste("No colors match query color

Then there are no obscure error messages like
showcolors( col="gren",pie=FALSE)
Error in segments(x0, y0, x1, y1, col = col, lty = lty, lwd = lwd, ...) : 
        first argument invalid
In addition: Warning messages: 
1: no finite arguments to min; returning Inf 
2: no finite arguments to max; returning -Inf
