In Song.xml, inside the ZIP XRNS, include the " ColorBlend":
<Tracks>
<SequencerTrack type="SequencerTrack">
<Name>violet</Name>
<Color>129,0,235</Color>
<ColorBlend>0.356000066</ColorBlend>
<State>Active</State>
<Soloed>false</Soloed>
<NoteColumnStates>
<NoteColumnState>Active</NoteColumnStat
...
...
It would be great if the skins XRNCwere compatible with " ColorBlend"! Something like this:
<Default_Color_01>204,0,0</Default_Color_01>
<Default_ColorBlend_01>0.356000066</Default_ColorBlend_01>
<Default_Color_02>0,153,25</Default_Color_02>
<Default_ColorBlend_02>0.356000066</Default_ColorBlend_02>
<Default_Color_03>0,68,255</Default_Color_03>
<Default_ColorBlend_03>0.356000066</Default_ColorBlend_03>
Thus, the creator of the skin has the power to change the color intensity of the tracks also.
To clarify, " ColorBlend" is configured here:
Preferences / Theme (Color only):
6803 
Pattern Editor / Tracks (Color & ColorBlend):
6802
