Object explorer in the VBE. Look up the color constants, specifically, xlColorIndexNone
<sup>edit</sup> Well, that's if you know what to look for... When you don't you can always do something like selecting a cell with no shading and typing ? activecell.interior.colorindex in the immediate window. And if you don't know to do that? Turn on the macro recorder and shade a cell and the unshade a cell to get the syntax. <sub>/edit</sub>
