RGBlotter is free, but I'd like to retain the copyright.
RGBlotter is a programming utility that lets you view and manipulate RGB colors in several useful ways.
The window displays a foreground and a background color and their components both graphically and numerically. There is a scroll bar for each component to let you change its value. You can also change the value by typing in what you'd like it to be.
The foreground color components are displayed on the left side of the window, and those of the background are on the right. Between these displays the foreground and background colors are displayed. Beneath them is a display contrasting them with sample text and simple graphics.
By choosing "Copy" from the Edit menu, you can copy the component value of the selected (where the insertion point is) component to the scrap. "Copy ForeColor" sends the red, green, and blue components of the forecolor to the scrap. "Copy BackColor" does the same for the backcolor. "Copy All" copys the values for both colors to the scrap.
"Settings…" lets you set the variable names you want to use for the fore- and back colors. It also gives you a choice of sending copies to the scrap in C or Pascal syntax. For instance, if you called your forecolor "pureWhite" and chose Pascal syntax, when you select "Copy ForeColor" from the edit menu, the scrap will contain
pureWhite.red := 65535;
pureWhite.green := 65535;
pureWhite.blue := 65535;
assuming those were the values you used. The C syntax would be the same, but without the colon before the equals sign.
Choosing "ForeColor >> BackColor" from the Colors menu replaces the background color with the foreground color. "BackColor >> ForeColor" does the inverse.
Using the dropper, you can "blot up" (thus the incredibly clever "RGBlotter") a color from anywhere on the screen. Choose "Dropper" from the Colors menu. The window will be hidden. The cursor will become a dropper. Find an interesting color somewhere on the screen and click on it. The RGBlotter will reappear with the forecolor set to the values of the color you clicked on.
If you have any trouble with RGBlotter, let me know. I'm "Logogrip" on America Online.
