Hi,
In the MWE below I define an rgb colour, myColor1, using random
numbers for the r, g and b components. I then use it to fill a
unitsquare the size of the page, which works as expected. In the loop
that follows I then use the defined colour, myColor1, along with white
and the variable r to create shades of myColor1 as in the MWE below.
However, myColor1 is not recognised in the loop and seems to be
replaced by black, although if I use a predefined colour, in this case
BurntSienna from the crayola collection, it works as expected. I have
tried a number of ways to get this to work as shown in the code but
without success. I would be grateful for any suggestions.
Best Wishes
Keith McKay

\definecolor[name="myColor1", r = uniformdeviate(1), g =

Remove the backslash in front of the definecolor command.
