Besides providing alpha value 0.0, Check for integer division vs float division as the method needs floats, so when you are dividing 88 (int) by a 255.0 (float) you are providing 0 instead of 0.34 for red value and similarly for green and blue.

You need to change alpha to 1, Alpha represents opacity ( transparency).

    [Q1 setTextColor:[UIColor colorWithRed:88.0/255.0 green:89.0/255.0 blue:91.0/255.0 alpha:1.0]];

You just forget to add alpha:1.0 :)

You probably wanted the alpha to be equal to 1 instead of 0 (zero means fully transparent, you might have misunderstood this...):

Q1.textColor = [UIColor colorWithRed:88 / 255.0f
                               green:89 / 255.0f
                                blue:91 / 255.0f
                               alpha:1.0f];

By the way, the title of your question is inaccurate. The text color is most probably changing, but you don't see the text since it's transparent.

Are you trying to make it transparent? You should try alpha 1. 

Q1.textColor = [UIColor colorWithRed:88/255.0 green:89/255.0 blue:91/255.0 alpha:1];

Do this as your color alpha is 0 means transparent

   Q1.textColor=[UIColor colorWithRed:88.0/255.0 green:89.0/255.0 blue:91.0/255.0 alpha:1];
