Using values for patterns and colors (FileMaker Pro Advanced)
The values for the patterns in the Line Pattern and Fill Pattern palettes are numbered consecutively, starting with the top row and counting from left to right, where the value for the pattern in the top left corner is 1. The values end at the bottom right corner with number 64. Five patterns in the first row can also be defined with words: NONE (= 1), SOLID (= 2), DKGRAY (= 6), GRAY (= 7), and LTGRAY (= 8).
Values for Line and Fill Pattern palettes
Note  The first pattern (value = 1) is transparent and the second pattern (value = 2) is solid. For objects with a color fill, be sure to use the solid pattern.
Themes use 6-digit color hexadecimal (hex) values to describe colors (for example, #CC9966), which can be found in most graphics programs that use a color palette.
Themes should use web-safe colors for databases that will be accessed by multiple platforms, displayed on monitors with varying resolutions, or displayed on a network. However, when your databases will be displayed on a single platform or at a high resolution, the full RGB color spectrum gives you a much larger and richer color set.
The Line Color and Fill Color palettes contain only web-safe colors. For information on using the color palettes, and on using patterns and colors in a layout, see Setting auto-resize options for layout objects.
