What is the specific ID for different concrete powder?

I have searched for the proper ID for specific concrete powder on various sources and it took so much time but I am not able to find it. I only get some information like ‘this is for concrete powder’ but it is not exactly what I want. It doesn’t provide specific ID for various colors. I know the process of creation of a pressure plate that can fit only on certain items. I am trying to make a map for which a pressure pad can only be placed on light grey concrete powder but without knowing proper ID for specific concrete powder it couldn’t be possible. But I found a Minecraft concrete recipe guide which helped me a lot. You can try this at your end.
