welcome to AZ, Tan chalk is great-Masters Tan chalk. It will make a green or blue table look horrible after an hour but that dosent bother me personally. It works as god asthe blue. Green chalk sucks IMO. I been playing 25 years and I use blue. I have some Tan because if i'm test hitting with a cue the shafts will stay clean. thats the other advantage it will make a shaft look clean fo a very long time where as the colored chalk will make a shaft look dirty, I'm old school and have blue shafts and live by blue chalk.
