I now am seeing red also, at version 10314.
Comparing SVG files for C and Ada on Example 1:
The file sizes are the same;
There are 535 differences;
Every difference (date excepted) is due to either
stroke="#FF0000"
or
fill="#FF0000"
in the Ada-generated file.
That's a lot of red.
The same experiment on PostScript files:
File sizes same
13 differences
Every difference is exactly due to
1.0000 0.0000 0.0000 C
in the Ada-generated file
where in the C-generated file there was
x y z C where x, y, z are floats of various values.
I'm going to take a wild guess that
r g b C
sets the color in PostScript.
Using the -cmap0 option, these files work correctly
cmap0_black_on_white.pal
cmap0_default.pal
cmap0_white_bg.pal
whereas this one makes red
cmap0_alternate.pal
Disassembling the red SVG file for Ada example 1 with a graphics
program shows a red rectangle for (I suppose) the background and
correctly-drawn plots but all in red. There is no text--no numbers on
the axes and no labels--but this is likely due to the graphics program
as is complains of missing fonts when I open the file with it.
Incidentally, the curve on the lower left-hand plot appears to be too
thick--about twice the thickness of the others--but this is also true
of the SVG result made with e.g. x01c using either the svg or svgqt
drivers. Also, those SVG files displace the "data points" on the upper
two graphs--svgqt upwards and svt downwards, but this is perhaps for
another thread.
Something happened between I think versions 10303 and 10312 to cause
all this red.
