Now that the basic animation is built, you can experiment with different inks. Inks affect the way a sprite is drawn, or rendered, against the images below it. Since Director builds each image from the lowest-numbered sprite channel up, the inks of the higher-numbered channels determine how those sprites appear against the complete image of all the sprites and the stage below them.
When two sprites—a text sprite and an image—are involved, ink can be applied to one or both sprites. If the text is on top, as is the case with the current score, the ink you choose for sprite channel 2, the sprite for the text, will affect the way the text is rendered on the image. You could reverse the channels to place the image in a higher-numbered channel and then modify the image ink, which would affect the way the image is rendered against everything below it, text and all.
