this page is about color........i hope.
color in html is in hexadecimal code. i was never good at math, but basically that means the amout of color is quantifed from 0123456789abcdef, 0 being the least and f being the most.the color code is also called the RGB value, R = red, G = green, and B = blue. here you have to remember the difference between "crayola" color and "light" color. in "crayola" color, the primary colors are red, yellow, and blue and you mix them in different quantities to get other colors. the absence of "crayola" colors gives you white; mix all the colors together and you (theoretically) get black.
"light" color is different. the primary colors are red, green, and blue. red+green makes yellow, for example. the absence of "light"(#000000), of course, gives you "dark," i.e., black; mix all the colors (#ffffff) and you get white. in RGB, you get two slots for each color, therefore really red text is #ff0000. really green text is #00ff00. in order to make a color lighter, you would want to add more of the other colors -- remember that all the colors make white.
for example, really blue text is #0000ff. in order to make light blue, i can't just use a lower number, say #000088, because that just brings that color closer to black, as we can see here. if i put in equal parts of the other two colors, say #1818ff, i should theoretically get a lighter blue. and so i do.
as you can see by the background color (#dfdc09), you can spend way too much time coming up with absolutely putrid colors by estimating (wrongly) how much you are going to need of each color to make brown or beige.
i don't know why i even care, since i'm a composer, not a graphic designer. i guess i just like to know how things work.
