Program One
What this applet does is match a greylevel on the left (0-255) with the white/black stripes on the right. The
button toggles the stripes to be horizontal or vertical. Move the slider to achieve an intensity match
(the left and right look about the same if you defocus your eyes). In
this manner, you can determine the gamma of your monitor.
Program Two
This applet is a color selector. Select the background color with the
picture on the left, and the text color with the picture on the
right. You can also change the text size, type, and style. The bars
on the right of the picture will change the colors on the picture to
be darker or lighter, in order to create more colors
Some of the code for this applet was found on the web. email me for
details.
