Make a UIColor with RGB values? or this might be a problem with loading my view...not

I recently decided i wanted to get rid of xibs all together and just create my view programatically. i am a little confused as to how to do this.

so i know you can use [UIColor colorWithRed:1.00 green:1.00 blue:1.00 alpha:1.00] to make a color (for that example, white) and instead of using the normal 0-255 scale they use the percentages for some reason which is fine.

to simplify this, i made a method in MainView.m/h (below) that accepted the 0-255 RGB values and returns a UIColor with those values:

Code:

- (UIColor *)RGBColorR:(double)red G:(double)green B:(double)blue {

    return [UIColor colorWithRed:(red/255.00) green:(green/255.00) blue:(blue/255.00) alpha:1.00];

}

I call it in my loadview method in my view controller:

Code:

- (void)loadView {
    self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];


    self.view.backgroundColor = [self RGBColorR:236 G:229 B:206];
     {...}

}
Note: I do not have a MainView.xib at all, I deleted it.

For some reason, it always comes up with a bright green color as the background and doesnt load of the text fields or buttons or anything i later add to the view. What is the proper way to do this... i am confused.
