When an item that can be tinted is given the consumable component (with has_consume_particles set to true), its particles will not be tinted the same colour as the item.
This affects leather armour, dyed wolf armour, potions, tipped arrows, coloured firework stars, and all types of tinted foliage such as leaves and grass. This would in theory also affect spawn eggs but, due to MC-269723, that cannot be observed.
How to Reproduce:
Use this command to give yourself a consumable leather helmet that has been dyed magenta:
/give @s leather_helmet[consumable={},dyed_color=16711935]Start eating it
Observed Behaviour:
The particles produced are always white, regardless of what the dyed_color value is.
Expected Behaviour:
The particles match the tint colour of the item.
