Yellow paint MULTIPIES.  What seems pale and calm on the swatch can become School Bus when the application is finished.  More so than any other color, yellow tends to intensify.  Exponentially.

I have rarely seen a true, pure yellow tone on a wall that I thought I could live with.  Yellows need to be browned out and lightened to be successful.  And mustards need the opposite treatment.  They need to be deep enough, and strong enough to hold up well when covered on walls.

Sherwin Williams has some nice golds, but Ben Moore’s Classic Collection is good for soft butters.  I have used their Cornsilk #198 successfully on more than one occasion.
