When you say double, do you mean you have two separate trays? Can you see all 3 at the same time?

And, what colors are the walls?

The GR has 2 tier tray & yea they are seen together. I hope photo below provides an idea of the area.

I have selected Behr in pale honey, which is a soft creamy yellow. Woodwork is white.

Paint the lowest trays in full color strength of the Pale Honey then the upper tray in a 50% reduction in pigment for the upper tray.

What color should I use on ceiling of trays ?

If I am understanding the photo the vertical portion of the trays is millworker painted white. Keep the millworker white and paint the ceilings the pale honey as suggested in previous post. If I have misinterpreted the photo, perhaps you could post more from different angles.

I planned on keeping crown molding white. I want to know what color to paint vertical wall between and the ceiling. I probably hVen't explained well.

Ok, so if I am now understanding this correctly, paint the wall/ vertical portions 100% pigment, paint the ceiling of the lower tray at 75% pigment and the upper tray ceiling at 50% pigment.

Thanks...
