[1.16.5] grass slab color based on GrassBlock

[perromercenary00]

Good days 
i need a grass slab a dirt slab and a stone slab to level the terrain after setting a village 
i basically copy the the slab class code and made the blockstate taking things from the grass block 

and this is the result

 

 

grass top is a gray png and something else apply colors based on 
and i dont have idea where it is 
the grassblock blockstate only has snow variant on it 

soo it has to be whit the render type 
   

        RenderType cutoutMipped = RenderType.cutoutMipped();
        RenderType cutout = RenderType.cutout();
        RenderType translucent = RenderType.translucent();
            
        
        RenderTypeLookup.setRenderLayer( Mblocks.GLASS_BLOCK.get(), cutoutMipped);
    

and google only gets me this 
int grasscolor = BiomeColors.GRASS_COLOR_RESOLVER.getColor(null, friction, explosionResistance);
and it dont lloooks likei could use that 

 

how i doo this slab to change grass color based on the biome or the grassblock

Use forge's ColorHandlerEvent(s), it is a client event.

 

For the logic used by vanilla see the BlockColors class.

you need to register a BlockColor for your Block inside ColorHandlerEvent.Block via BlockColors#register,

it's recommended to implement the BlockColor interface using a lambda expression

(Edit) In addition the BlockColor returns the color via a int, if you want the vanilla behavior you can use BiomeColors.getAverageGrassColor
