On the AL, we have health debate about the Pulse Rifle color. It was Humbrol 170 Bess Brown, but looks OD Green in the film.
I guess "Tardis Blue" is even more of an enigma. Is it paint or stain? It looks blue on TV, but purple in real life. Are you mixing up an ounce for a model or a gallon for a full size Tardis. Which tardis/doctor/year. I have done a bunch of searching here and on tardis builders. It seems that people use a variety of different options.
So I thought I would start a thread here just for paint options.
I am going to use one of the HomeDepot Behr paints and then try to age it with a black rub/dry brush. Either S-G-560, 570, or 580 Jazz Blue, Sapphire Lace or Running Water.
Please post any other paint you have tried.
