Getting the colour of any point on a plane?

I want to find the colour of a point on a MeshFilter. I know I could get an array of vertex colours from meshFilter.mesh.colours[] but these are just an array of colours of each individual vertices. Sometimes the colour of a point between 2 vertices are interpolated and so it wouldn’t be accurate to just get the colour of one particular vertex.

How can I find the colour of any given point on a plane with a MeshFilter component?

Right, so what you can do is to interpolate the color yourself based of the three color values of the triangle. I don’t know how you pick the point in your mesh, but if you for example use a raycast and get a ray cast hit, you could use the barycentric coordinate to interpolate it pretty easily. See the example in the docs for RaycastHit.barycentricCoordinate that does this for a normal for example.
