The perfect Yellow.White Raisin by Sherwin Williams. its sherwin williams white raisin, and i normally get it in a satin. SW has tons of different paint products, anyone of them is good. For the sealer, i like woodclassics by sherwin williams.
Chalkboard desktop for inspiration. You could use 3 coats of Graphite Chalk Paint by Annie Sloan for the chalkboard, and Emperor's Silk for the desk. I like it all except the chalkboard top. Would like to paint my desk it is similar.
