Dear UseRs and DevelopeRs
It would be helpful to see the color palette available in the
venneuler() function.
The relevant par of ?venneuler states:
"colors: colors of the circles as values between 0 and 1"
-which explains color specification, but from what pallette? Short of
trial and error, i'd really appreciate if some one could help me locate
a "0 - 1" pallette for this function to aid with color selection.
The color spec stored in the VennDiagram object is multiplied by 360 to
give the "hue" component of an hcl() colour specification. For example,
0.5 would mean the colour hcl(0.5*360, 130, 60)
Alternatively, you can control the colours when you call plot, for
example, ...
plot(ve, col=c("red", "green", "blue"))
... should work.

FWIW, i tried the below code and received the displayed error. I failed
to turn up any solutions to this error...
Any suggestions appreciated,
Karl
library(venneuler)
ve<- venneuler(c("A"=1, "B"=2, "C"=3, "A&C"=0.5, "A&B&C"=0.1))
class(ve)
[1] "VennDiagram"
ve$colors<- c("red", "green", "blue")
plot(ve)
Error in col * 360 : non-numeric argument to binary operator
