Not a bug: color and transparency are not the same thing.

True, but you define and use them at once. How to separate them then?

Did you look at http://wiki.contextgarden.net/Color/Transparency ?

Thanks for the pointer. The simple solution is just to also define the parameters 't=1,a=1' for the opaque color. Should be mentioned in the docs somewhere and sorry for the noise ;)

Hi,

the nested color inherits the transparency from it's surrounding color.

\definecolor[colA] [r=0,g=0,b=0.01,t=0.2,a=1] % transparent \definecolor[colB] [r=.278431,g=.235294,b=.545098] % opaque

\starttext \startcolor[colA] \definedfont[SansBold at 96bp]Titanfall\, \startcolor[colB]2\stopcolor \stopcolor \stoptext

Maybe intended behaviour, maybe a bug. Donno.

colorspace, color and transparency are different axis

\definecolor[colX] [r=.5] \definecolor[colY] [t=.5,a=1]

\starttext

\startbuffer \dontleavehmode \blackrule[color=colX,width=3cm]\hskip-1.5cm \blackrule[color=colY,width=3cm] \stopbuffer

\getbuffer \par \color[colY]{\getbuffer}

\setupcolors[rgb=no]

\getbuffer \par \color[colY]{\getbuffer}

\setupcolors[rgb=no,cmyk=no]

\getbuffer \par \color[colY]{\getbuffer}

\stoptext

it just happens that coming from mkii colors can have transparencies

as Alan says: they are different things (also in metafun)

\startMPcode fill fullcircle scaled 4cm withcolor "red" ; fill fullcircle scaled 3cm withtransparency (1,0.5) ; fill fullcircle scaled 2cm withcolor "green" withtransparency (1,0.5) ; \stopMPcode

Thanks for the clarification. Stupid me :D
