[Complete] Bionicle Tahu Cosplayer from Series 29

That's because BL for some reason insists on using the hips colour as base colour, not the legs. In LDraw hips are only colour 16 if they match the legs colour (which they don't in this case). The "Boots" for dual-molded legs also never count as the base colour here.

EDIT:
Lego also mostly considers leg assemblies to be based on the colour of the legs (some exceptions though):

Remember, Bricklink isn't offiicial - and in this regard they are likely wrong

Rebrickable does the same as BL: https://rebrickable.com/parts/970c02pat2...nes-print/
The principle is that the hips is the base subpart, legs (or pegs…) are added to this base.  Same for torsos.
LEGO’s rule would be “last subpart added to the assembly gives the colour,” hence torsos with Yellow hands are considered Yellow.

Also, LEGO has some special colours (I’d say about 100!), like “1.multicombination” for marbling or dual-moulding….  You can see them on https://brickcolor.net/ if you choose “Show all TLG colors.”  LEGO is a mess
