You can disable this feature by setting the `drop` field of the node
to itself (without metadata).
To transfer the color to a special drop, you need a drop table.
Example:

minetest.register_node("mod:stone", {
description = "Stone",
tiles = {"default_stone.png"},
paramtype2 = "color",
palette = "palette.png",
drop = {
items = {
-- assume that mod:cobblestone also has the same palette
{items = {"mod:cobblestone"}, inherit_color = true },
}
}
})
