Re: [NTG-context] Define color with calculations
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

Re: [NTG-context] Lines in \showbodyfontenvironment
I have tested it on this code:
\definebodyfontenvironment
[default] % or size
[text=10pt,a=2,d=5, % or other values
]
\starttext
ahoj {\bfa ahoj} {\bfd ahoj} ahoj
\showbodyfontenvironment
