problem with label color

[aidji]

Hi i have a problem with my scripts(im very begineer):
my problem is with Floating text driver with this line:

1. ft.Init ( textValue, testColor , target );

testcolor set the value of my prefab label, but i dont see the label displaying correctly! and i change it to

1. ft.Init ( textValue, Color.gray, target );

it works fine but i would have this value changeable through variable.

You know NGUI has HUDText extension which basically is floating text, right?

[aidji]

yes but my script is really more basic and i cant buy it im saving money for Tnet plugin , it work just i dont know how to change colors through public variables, it make my text being transparent when i change it color

actually my solution is to duplicate to script on an other prefab and change the color.yellow to white for exemple

[ArenMook]

Yellow to white? o_O What shader are you using on your text?

[aidji]

my meaning is i dont want to change the color of the label (its the default label widget made by NGUI, so i didnt added or changed shader)

actually my method is:
one prefab with  ft.Init ( textValue, Color.gray, target );
a second prefab with a second script where is change only Color.white

and i instanciate both of them when i need..i believe its a stupid way to do, but i dont believe a way to pass the color value through a public variable
