Identical vehicles were used throughout the trials, in fact to keep the trials 'blind' the placebo vehicle was coloured the same standard shade of pink that Nizoral is manufactured to (pantone 1767 C), this is believed to be one of the possible factors behind the 'residual homosexuality' figure in the placebo group. It has been know since the mid 1970s that heterosexual men can be 'gayalized' with repeated exposure to the colour pink with spectral wave lengths of 750 nm or less, most test subjects suffering from being 'bent queer'respond well to blue spectrum light of around 400 nm.
