You are welcome. You may be interested in the new Makie.voxels function if your colors are restricted to a pre-defined set of colors:

> The new voxels function was introduced in Makie v0.21 to plot 3D Cartesian grids more efficiently. However, it assumes Array{\<:Real,3} for the colors. Can it sill be used with general Colors.jl colors? It is easy to convert Gray to Real, but multi-channel colors (e.g. RGB) cannot be converted to Gray without loss.

It can render larger grids based on that assumption.
