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]
\starttext
\colored[r=\cldcontext{0.5*0.7}]{\cldcontext{0.5*0.7}}
Thanks, Henri! Works like a charm.

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
