Is there any built-in way to do that? I also have an Idea to render 8 single-color copies of item model around original one, but in this case I need to find a way to render a single-color item (i.e. no texture, just a silhouette)

what's the context? is the item yours or vanilla? where do you want to render it? is it an item stack?

Item may be both mine or vanilla

As title says, I want to render it in GUI

yes, ItemStack

Current render code

        this.itemRenderer.zLevel = 100.0F;
        for (ResearchTableEntity.ItemState state : container.researchTableEntity.getItemStates()) {
            this.itemRenderer.renderItemAndEffectIntoGUI(this.minecraft.player, state.item, tableRect.x + state.pos.x - 8, tableRect.y + state.pos.y - 8);
        }
        this.itemRenderer.zLevel = 0.0F;

hm, I'm thinking you could use of a shader, there may be a simpler way which I'm not aware of;

Silhouete and outline are different things, to shade for a silhoute you could render any non-tranparent pixel of the item texture as black (or whatever color you'd want for the silhoute. actually, if you grayscaled the item texture you could tint it to whatever monochrome color you'd want). shaders for outline are a little more complicated, but not much, you can find info on such shaders online

again, there maybe be an easier way to do it, but I'm not sure
