Flowing colours

Greetings,
I am wondering about how I could make coulour flow through something in flash… wow that was a bad discription, lemme try again. For example say u have the word Welcome, and at first the letters have no fill, but then a colour shoots through them… I don’t think it could be done with text, maybe you have to create your own graphic that is the word… I donno, neway, if you can understand my tired ramblings give me a shout…
thanks

Do you mean “color shoots through the text” Like it flies in from the left or somewhere?
I’ve got feeling you’re talking about masking…

Ya I’m pretty sure it involves masking, and shape tweens… I’ll try to figure something out, I was just wondering if anyone had ever had any experience doing it and could help me with it. Ya I do mean shooting through the word;through each letter fast… and then moving to the next letter
