Don't like the color palette provided by Notes? Long for an attractive background color for your form? You're not
alone. Compose your color in an Illustration program and save as a small, solid square, about 25x25 pixels. Then in the "Design - Form - Properties - Background" import the graphic to achieve a more aesthetically pleasing background color. Use a similar technique for shaded backgrounds. Create a graphic about 20 pixels by 1000 pixels and create a box with a linear fill from your primary color to the transparent color. When this background is imported in Notes, your form will have an interesting transition in the background.
