FF = 255 not 256...

FF = 255 because of the reason I explained earlier. The left F is 15 x 16 = 240 and the right F is 15 x 1 = 15 which makes 240 + 15 = 255.

00 = 0 because the left 0 is 0 x 16 = 0 and the right 0 is 0 x 1 = 0 which makes 0 + 0 = 0.

You think zero shouldn't equal zero?

is this the dark side of hexadecimal?

why does FF = 256?

and 00 == 00?

:S somethings is very wrong here (IMO)

Now that's confused me!

Ok, think about it this way.. each char in a hex goes from 0 (0) to F (15) so that's basically 16 numbers (if you count A-F as numbers). Now, if you put 2 hexadecimals next to eachother (i.e. A5 (we'll call them "left" and "right")). Since 2 hex are and the right number can only go as high as 15, the left one will be the next number in like which is 16. So...

0F = 15 (0 x 16 + 15)
10 = 16 (1 x 16 + 0)
35 = 53 (3 x 16 + 5)
AA = 170 (10 x 16 + 10)
F0 = 240 (15 x 16 + 0)
FF = 255 (15 x 16 + 0)

Ok, so we're done with 2 hex next to eachother and notice that FF is 255 and of course the next number is 256 (16x16) which means that if Hex the next number would be 100 (1 x 256 + 1 x 16 + 0)

I hope that makes more sense now...

then how come 16 x 16 = 256? is it coincidence or what?
if a 16 does excist then where is it?
and how do u convert from RGB to hexadecimal and back again?

.. o and btw i dont' get the t-shirt thingy...

That's a great T-shirt and yes I did get it without explaination!
