hex colours

hi i know this a bit of topic but you guys are so helpful :D does anyone know about hex colours and how i can find out about them?

What do you want to know about them ?

basically what colours relate to which sequences etc...
eg i think #FFFFFF is white isn't it?
sorry if im being a bit lazy ;) just thought there might be a simple logical way that they are assigned

Just to let you know there is a color picker inside of flash, but:

i cannot thank you enough m8 :)
however i need silver/grey and pale blue + couple variations and there no silver/grey on the palette lol oh well ;) but you got me strated cheers m8 :D

is it possible to obtain the hex code for a colour that you have selected in photoshop 6? im sure there must be but have had little luck finding it

what a **** i am it was there all along on the colour picker frame sorry to have bothered you :(
