I want to try my hand at creating a roof with tiles on it.
How would I go about it color-wise?
Do I make the roof light or darker? Or do I make the tile lighter or darker?
You can make roof tiles with custom made mesh parts and rotate them different degrees i would try adding variation of colors to the tiles you could use parts to get that heavy detail to the roofs of the house. Lighter color depends on the color pallet of your house real life buildings normally feature dark vibrant colors such as gray - orange - brown and more texture that I would apply to the roof instead.
If your wanting to use parts it’ll take some time with experimenting and finding a proper theme your wanting out of this
Using a texture can produce a decent result. I would use real life builds to get a general idea on the color pallet your wanting for the roof, tiles do come in different shades of colors you can switch it up to have a good approach or have a darker grey color duplicated on the entire roof.
I feel that when it comes to shingles of a house you are going to want to adjust the color based on the house. For this house I would say that it should be a little bit lighter than the base roof but not too light. When it also comes to shingles I suggest that you overlap one over the other to make it as relistic as possible in design and lighting. Also you might want to add more detail to that part or else the roof is going to look like one extra part.
