Hi, When I use definecolor, (how) can I use computations in setting the value of a component? Something like the following... \definecolor[mycolor][r=0.5*0.7] Thanks, ~MHB
Use Lua. \def\eval#1{\ctxlua{% local context = context local _ENV = math context(#1) }} \definecolor[mycolor][r=\eval{0.5*0.7}] \starttext \color[mycolor]{Hello!} \stoptext On 18/02/19 4:37 PM, Mohammad Hossein Bateni wrote:

Thanks, Henri! Works like a charm.

Better use \luaexpr. From the manual: The \luaexpr command can also better deal with for instance conditions, where it returns true or false , while \cldcontext would interpret the boolean value as a special signal. Although I think my solution is superior because you can just type \eval{1.0*sin(pi)} instead of \eval{1.0*math.sin(math.pi)}
