There are four elements in TileDreams that have a color property available to the user.
These elements are the tile's fill-color, the tile's outline-color, the
background-color, and the highlight color.
Each of these defined colors are retained by the preferences file.

Use the color palettes with the mouse to assign these properties. Color cloning is covered elsewhere in this manual.
If there are no tiles selected, and the Focus control is set to one of the two
tile-parameters, the current tile will be changed. This will modify the template
upon which all subsequent tiles are based until you change it to something else.
If the focus control is set to one of the two tile parameters, and there are tiles
selected, those tiles will be changed. The current tile remains unaffected.
Palettes
The standard version of TileDreams supports an astonishing 262,144 colors, through the
use of a customizable palette. The registered version of TileDreams includes a
palette of 216 web compatible colors, in addition to the RGB Sliders.
RGB Sliders
 |
The Color Definition Palette is adjusted with 3 slide-controls. From the top down,
these sliders represent the red, green, and blue components of each pixel.
When a slider is adjusted, a gradient fill is defined in a 128-pixel square region,
directly above the sliders, for the user to choose from using their mouse, as with an
artist’s palette.
While you drag your mouse over the palette, the area behind the sliders will reflect
the current color indicated by the mouse position.
Each group of 4 pixels (2 x 2) in the palette is a different color. Really.
As with color television, each pixel on your computer monitor has a red, green, and
blue component. In VisualBasic (and other programming languages), each of these components
has 256 degrees of intensity, which means there are over 16 million possible combinations
(256 3).
Displaying this range of colors to a user would require a monitor that was nearly 57
inches on each side, each pixel representing a different color. Human eyes are not nearly
as discriminating as the current technology would suggest. The number of choices presented
by TileDreams to the user is 262,144 (64 3), with 192 different possible
palettes (64 x 3).
The RGB Slider palette works this way: Imagine a cube of pixels. The three
dimensions of this cube (height, width, and depth) are represented by increasing amounts
of red, green, and blue. When you let go of a slider, TileDreams retains it's
position, and proceeds to generate all the possible combinations of color when moving the
OTHER two sliders.

216 Web Compatible
 |
The 216 Palette is a fixed bitmap within TileDreams, and was generated
during development. The colors were generated using all possible combinations of
Red, Green, and Blue with 6 possible positions on the scale of intensity (1 to 256), at
intervals of 51: 1, 52, 103, 154, 205, 256
This gives us a theoretical cube of colors 6 X 6 X 6, for 216 possible. This
assortment of colors is compatible with most browsers, and is the easiest way to ensure
that all users will be able to see your images the way you intend
