roulette double bet

[mmmmmbrother]

in roulette there is a hideous house advantage.
doubling your bet every time wont work because of this.
but what about trippling your bet everytime.
looking at red/black;

if you keep betting on black
bet 1, lose
bet 3, lose
bet 9, lose
bet 27, win.
so you spent 40 dollars but won 52 ?

or do you only get 1.5 to 1 odds for betting on colours


the only problem i can see with this is the bet limit.
