First make a transparent color, and then use it to color the ribbon.
There are a few approaches.
(A) Menu way. Transparent colors can be created interactively in the
(under Tools... Utilities)
and then Actions... Color... from editor uses that color. You can
set the target to
ribbons only if you want (Actions... Color... ribbons).
(B) Command way. Transparent colors can be created with the command
colordef transred 1 0 0 .3
colordef transblue 0 0 1 .3
and then used with the command "color"
color transred,r :1-10.a
color transblue,r :1-10.b
(you could go back and adjust the colors with colordef at this point
as needed, and the items will adjust their colors without another
The color command can also use the Color Editor color (that color can
be indicated with the name "fromeditor" or "colorpanel").
This process differs from making a surface transparent for technical
reasons - in a nutshell, a surface patch has a transparency property
that is separate from its color, while a ribbon segment does not.
I hope this helps,
