[1.15.2] Incorrect leaf colours

[Bahnschrift]

I'm using Autumnity mod, which adds some bright orange, red and yellow leaves to the game. However, these render as green with dynmap after using DynmapBlockScan.

DynmapBlockScan produces this:

texture:id=txt0007,filename=assets/autumnity/textures/block/maple_leaves.png,xcount=1,ycount=1
texture:id=txt0008,filename=assets/minecraft/textures/colormap/foliage.png,xcount=1,ycount=1,format=BIOME
block:id=%yellow_maple_leaves,data=0,data=1,data=2,data=3,data=4,data=5,data=6,data=7,data=8,data=9,data=10,data=11,data=12,data=13,patch0=0:txt0007,patch1=0:txt0007,patch2=0:txt0007,patch3=0:txt0007,patch4=0:txt0007,patch5=0:txt0007,blockcolor=txt0008,stdrot=true
block:id=%maple_leaves,data=0,data=1,data=2,data=3,data=4,data=5,data=6,data=7,data=8,data=9,data=10,data=11,data=12,data=13,patch0=0:txt0007,patch1=0:txt0007,patch2=0:txt0007,patch3=0:txt0007,patch4=0:txt0007,patch5=0:txt0007,blockcolor=txt0008,stdrot=true
block:id=%red_maple_leaves,data=0,data=1,data=2,data=3,data=4,data=5,data=6,data=7,data=8,data=9,data=10,data=11,data=12,data=13,patch0=0:txt0007,patch1=0:txt0007,patch2=0:txt0007,patch3=0:txt0007,patch4=0:txt0007,patch5=0:txt0007,blockcolor=txt0008,stdrot=true
block:id=%orange_maple_leaves,data=0,data=1,data=2,data=3,data=4,data=5,data=6,data=7,data=8,data=9,data=10,data=11,data=12,data=13,patch0=0:txt0007,patch1=0:txt0007,patch2=0:txt0007,patch3=0:txt0007,patch4=0:txt0007,patch5=0:txt0007,blockcolor=txt0008,stdrot=true

As far as I can tell, the base texture (maple_leaves.png) is colourless, and in game has it's colour set by code instead of by a colourmap, DynmapBlockScan assumes that it is using a colourmaps and gives dynmap the vanilla colourmap (txt0008).

Since DynmapBlockScan can't seem to detect the colour, a potential fix could be to manually set the colour. Is there any way to do that?
