You can use gradient colours in Adobe Flash CS6 for shapes that you have drawn using the pencil/brush tools or the shape tools. You can create two types of gradients: Linear gradients and Radial gradients. Gradients can combine two or more colours and you can customise the distance between the different colours as well as the angle they follow. You can specify the colour gradient when you create a shape or later on by filling with the paint bucket tool. Watch the video below or click here to view it on YouTube.
