Hello out there,
in a BLT graph I want to obtain lines with different shades of red. So
I set the colors to #ff0000, #ff1d1d, #ff3a3a etc. - but all lines
appear in a plain red (like #ff0000).

Is there anything that can be done about this?
Any help will be greatly appreciated.

If I understand this, you want one of more elements with different
colors.  If I misunderstand, can you show an example of your code?

There should be no different whether you are using the RGB value
(e.g. #ffffff) or color name (white).

        .graph element configure line1 -color red1
        .graph element configure line2 -color red2
        .graph element configure line3 -color red3
        .graph element configure line4 -color red4

        .graph element configure line1 -color #ff0000
        .graph element configure line2 -color #ee0000
        .graph element configure line3 -color #cd0000
        .graph element configure line4 -color #8b0000

If you want the same element to have different color line segments,
that's different.  You'll need to set up a weight vector (you can
reuse the y-vector) and a style mapping.  You can look at
demos/graph2.tcl as an example.

Sorry, my fault. Maybe the shades I used were too close to each other,
or the light was bad (and then it was awfully hot yesterday) or maybe
I should have my eyes checked - in any case, BLT is just doing fine.

Best regards
