Color Strip
This color strip is generated by dividing the numeric color code for white (which has the highest value) by the number of shades you select. That ratio is then used as the increment from one shade to the next in the color strip. Each strip starts with black (which has a color code of zero) and goes toward white. Red tends to be toward the right since it it had the highest place value in the hexadecimal (base 16) color system. However there is no reason red needs to be in the highest place value position. As a future update to this program, I plan to let the user decide what order they want to put the colors in. The base 16 color system uses 2 digits to represent each color: RRGGBB, where RR stands for the code for red, GG is the 2 digit code for green, and BB is the code for blue. Here are some interesting experiments to try:
- What happens if you put in a number of shades that divides 255 (one less than the number of shades possible for each color or you could think of it as the number of shades where the zeroth shade is the absence of color)? Why?
- What happens if you put in a power of 2? How high do you have to go before you see green? How about blue? Why?
- Have you found any other interesting patterns? If so, please e-mail me and let me know about it so I can post more questions here.
