Natural wax, lightly filtered and refined by separating in water or using a solar melter, is going to be some shade of lemon yellow. The bright sunny color is very attractive.
Color comes from various natural contaminants, primarily pollen, both as particles and absorbed as fats on to the wax. The color varies with the hives harvesting (a lovely, and well worthwhile older Canadian review of wax properties notes Nova Scotia produces red wax because Dandelions are the primary nectar see-- http://link.springer.com/article/10.1007/BF02609202#page-1
). No amount of home-scale filtering is going to remove pollen grains and absorbed fats are integral to the wax.
The famous red varnishes of Stradivarius violins had beeswax/propolis mixes to seal the wood (and color it). Perhaps dandelion or henbit is the secret to great music.
Wax can oxidize with heat, exposure to metal, acids and rosins can decay. Industrial uses: molding for casting, spraying on fruit, etc demand highest purity and a neutral reaction. This wax is bleached (primarily with hydrogen peroxide, per recent patents) and chelated to remove contaminates which cause the wax to crumble.
There is no need to use hydrogen peroxide on your home wax, but you can substantially brighten dull brown wax with it as an experiment.
