I have ordered until now only white and black flashunits

i find other colored flashuntts (mint,orange,yellow) cool

but I think they will make colorcast if use with reversible umbrellas

it is true or not ? i have not yet a colormeter and can not meter it

There is not a color cast generated by the unit housings. By and large, any light reflecting off the housing would reflect away from the subject. Even still, this light would be of so little consequence, if it did reflect toward your subject, it would still not impact the color cast. Color from clothing, walls, carpet, etc., would be of a bigger concern.
