In PGF manual almost in all examples red!50!white
this type of syntax is used, however I find it very difficult to write it in this syntax to get desired color. Tikz uses xcolor package for coloring and xcolor has RGB,HTML
and many other color models,but it does not mention anything about the syntax of using those color models in Tikz.
Is there any way to use these modes in Tikz and it will be very helpful if I can also use transparency parameter like alpha
in RGB
and opacity
in HTML
.
Here is the minimal example you can modify
\draw (3in,-3in) node [draw,fill=red!50!white,shape=trapezium,trapezium left angle=40,trapezium right angle=-40,minimum height=1in,minimum width=1in,trapezium stretches=true,text width=0.58in,align=center] {Lorem Ipsum};
