HTML Challenges Asking For Color Given Hex Values
While doing HTML challenges lately, I've come across some questions where you are given a 6 digit hex value like #454545 and you need to name the color. I'm not exactly sure how you'd get the question right wothout searching it up online or something and it doesn't even seem related to what we've been learning in the HTML course at all other than the fact that they're Hex codes you can use for the color and bgcolor attribute in HTML. I think these types of questions should be removed.

Hexadecimal color's code are quite simple to understand, with:
#00 00 00
You will have black... but why?
Because you have to read it that way:
#RED GREEN BLUE
#00 red 00 green 00 blue
Then you have no color... basicly it's black.
0 is smallet value, F is highest.
#FFFFFF is sum of max RED, GREEN, BLUE, which is white.
Have a look at it: http://common.ziffdavisinternet.com/encyclopedia_images/RGB.GIF
So if we type:
#FF0000
You can read it that way:
#100% red 0% green 0% blue
...it's red then.
#FF00FF
#100% red 0% green 100% blue
blue + red => purple
and so on :)
So #454545
...same amount of red, green, blue... not 0, not F... between both value, you will have grey shade.

The colour codes I've come across are ones of general knowledge, such as #000000 and #FFFFFF or #FF0000.

A shortcut that you can use for hex codes is that if the code is repeating, you can use #000 or #FFF. You don't have to type out the full hex code.
