How to get this finish?

[Infsub]

Hi all. I have built several maple cap guitars and finished by using black to pop grain sand back then colour, clear etc.

My next project is an ash build.
Somewhere on here I saw a green guitar that had a yellow grain pattern that got me thinking.

I would like to have the ash grain yellow and then do a translucent blue using metal cast paint over it. (used this stuff before and it works great)

So to get the yellow grain beneath the blue, should I stain/ dye the body yellow, sand back and then spray the blue to the desired level of colour/translucency?

Or do the yellow, sand back, coat with something (clear/poly/Shellac) and then spray the translucent blue?

I know each way may end with greenish grain but the guitar I saw somewhere in one of these
pages has yellow showing through green so I am thinking there has to be a way to achieve this with out putting myself through the pain of trial and error.
