In this case, yes, but I also have white, yellow, red, green, and orange.

Specifically, Crayola sidewalk chalk.


-Look down through the strings and determine the strike point line. Put 
some tuning wedges along it.
-Pull the action
-Rub the underside of the string with the chalk along the strike point 
line. PLAIN WIRE ONLY - DO NOT TOUCH WOUND STRINGS!!
-Replace action and firmly play all chalked notes.

Enough chalk will remain on the strings to leave string lines on the hammers.

I originally learned this as a method to check una corda spacing, but it 
can show a host of other things related to hammer/string mating such as 
filing or string level by noting the relative lengths of the marks.

BTW, the stuff IS messy, so have a cloth handy to wipe your hands, 
etc.  Doing it in a room with a white carpet might not be the best idea, 
but since it is a powder it should only prove the efficacy of a vacuum. ;-}
