If i put this code

for (I=1;I<8;I++)
there will be 8 loop
can I change as example the color of the text each loop with different color?

yes
The basics for changing a TextObject colour is

MyColour=RGB(Red,Green,Blue)
TxtObject.SetColour(MyColour)

OR
TxtObject.SetColour(Red,Green,Blue)

where Red/Green/Blue is an integer 0-255.
(255,0,0) pure red, (0,255,0) pure green---etc

You could then put an 'if' statement inside the loop to set MyColour to a different colour for each loop.
In this way, you can define the precise colour for each loop of the count.
