These are my results for the brightest stars, plus a few dimmer, but colorful
stars:

Reed's formula is a better match at bluer than -0.1, although it still isn't
very good. Both formulas are good up to about 1.0, and Ballesteros' is better
for the reddest stars.
The B-V values were copied directly from the Yale Bright Star Catalogue, 5th
edition; and the temperature data are from Wikipedia, which in turn got its data
from a variety of sources.
