Modify Color Dialog, True Color Tab

Used to select a color using True Color values.

The graphical, textual, and numerical controls let you select colors using a number of different color models. Because there is a direct relationship between the color models (they all define the same color, but in a different way), a change to any value in one model causes a change to one or more values in the other models.

Setting	Description
Tint	The "rainbow" of colors controls tint (hue and saturation). The left side of the rectangle is fully saturated with color; no whiteness is mixed in. To the right, the saturation level drops off as whiteness is added. Within the rectangle, an inverse "X" pointer marks the selected tint. Dragging the pointer changes the tint. The position of the pointer corresponds directly to the Hue and Saturation fields if HSV is chosen as the alternate color model.
Shade	The shade rectangle (to the right of the tint rectangle) controls shade or brightness for the specified tint. The rectangle ranges from all black at the bottom to the specified tint at the top with decreasing amounts of blackness along the way. A horizontal bar that extends across the rectangle marks the selected brightness. Dragging the pointer vertically changes the brightness. The position of the pointer corresponds directly to the Value field if HSV is chosen as the alternate color model.
Eyedropper	To select a color using the eyedropper, click the eyedropper, continue to hold down the mouse button, drag your cursor to the location of the desired color, then click OK.
Color Model	You can also set the color based on any of these color models. The models provide different ways to specify the same color; the color set is the same regardless of the model used. RGB (red, green, and blue) — MicroStation's internal color model. Red has a valid range of 0 (no red) to 255 (full red). Green has a valid range of 0 (no green) to 255 (full green). Blue has a valid range of 0 (no blue) to 255 (full blue). HSV (hue, saturation, and value) — The Hue, Saturation, and Value controls work similarly to a color TV's tint, contrast, and brightness controls, respectively. The HSV model is generally the most intuitive for those with no background in color theory. Hue has a valid range of 0-359. Saturation has a valid range of 0-100. Value has a valid range of 0-100. RGB (0-1) — The valid ranges of Red, Green, and Blue are 0-1. CMY (cyan, magenta, and yellow) — The valid ranges of cyan, magenta, and yellow are 0-255. Cyan, magenta, and yellow, along with black, are the colors used in four-color process printing.
Color Components	The color components control the relative amounts of red, green, and blue for each custom color.
