VGA COLOR
A VGA Palette Changer

WARNING: THIS PROGRAM IS TO BE USED ONLY WITH 16 COLOR VGA AND SUPER-VGA DRIVERS
Do you run Microsoft Windows with a VGA or Super VGA card in 16 color mode? Did
you know that your card is capable of selecting those 16 colors from a palette
of 262,144, but you are forced to use those 16 colors that the manufacturer
happened to favor? The VGACOLOR utility will unleash the full capabilities of
your VGA or Super VGA hardware.
If you run Microsoft Windows with a VGA or Super VGA card at any resolution
with 16 colors, then the VGACOLOR utility will let you select the 16 pure
colors from a choice of 262,144. You can make your blues deeper or your
whites grayer. Setting colors to your choice will not only help your vision
but also reduce flicker on many monitors (bright colors seem to flicker more
than darker colors).
To use VGACOLOR, simply copy the files VGACOLOR.EXE, VGACOLOR.INI,
VGACOLOR.TXT, and VGACOLOR.WRI to a directory (for example, c:\utils\vgacolor).
Then, using the "Run..." command of the Program Manager or other shell, simply
run VGACOLOR.EXE. Or, if you want, you can install the VGACOLOR icon in a
Program Manager group (for example, in the Accessories group) and double click
on the VGACOLOR icon. This will cause a fairly self-explanatory dialog box to
be displayed.
At the top is a group of 16 boxes, each with a different pure color. Select
the color you wish to modify by clicking on the corresponding box. The box to
the extreme left indicates the color currently selected. If you don't have a
mouse, you can type in Alt-C (hold down the Alt key and type in C, then
release both), and then use the arrow keys to move among the 16 boxes. When
you have moved to the color you want to select, press the space bar. In either
case, the three scroll bars will indicate the current Red, Green, and Blue
values of the selected color.
To change these values move the appropriate scroll bar. If you don't have a
mouse, you can either tab over to the appropriate scroll bar, or press Alt-R
for red, Alt-G for Green, and Alt-B for blue, and then use the left and
right arrow keys to move the scroll bar control. When you have set the colors
to your liking, press the OK button. If you want to abort the color change,
press the Cancel button.
Ok, so what's the Save button for? VGACOLOR lets you save the current settings
so that you can load them at startup time. VGACOLOR is a shareware utility, and
this feature is not enabled until you register the product with the author. A
registration of $15 is requested, and will go towards many more hours of
hacking and a formal education. If you have a registered version of VGACOLOR,
you can simply put "VGACOLOR.EXE" in your "load=" line in your win.ini file,
and VGACOLOR will automatically set the colors to your settings when you start
windows. It will not display any dialog box, and will not take up any memory.
The VGACOLOR utility is also a polite utility - it does not change your win.ini
file. Nor does it require you to put certain files in the already overloaded
windows directory. All VGACOLOR.* files can be put in a separate directory.
If you decide not to continue using VGACOLOR, simply delete VGACOLOR.* from
the directory in which you installed it, and your setup will remain unmodified.
Disclaimer and Warning:
VGACOLOR SHOULD BE USED ONLY ON VGA AND SUPERVGA CARDS WITH 16 COLOR DRIVERS.
Attempt to use it on other cards and with drivers other than 16 color ones
might cause the system to cease functioning. The author is not liable for any
damage, direct or indirect, arising from the correct or incorrect use of the
VGACOLOR program. Use of the program constitutes agreement with this
disclaimer and absolves the author of all liability.
How to register:
