Color picker tool?

I am not a web designer. I am using Blogger/Blogspot.com and the Minima template.

The template has this css -
a:link {
color:#58a;
text-decoration:none;
}
a:visited {
color:#969;
text-decoration:none;
}

(a) I don't understand the #58a and #969 codes

(b) I want a free online/offline tool where I type the code say #58a and it shows me the color and Vice-versa ie. I click on a color and it shows me the code. Note the code here is three digits. The tool should display both three digits and six digits.

Any pointers? Thanks.

 

#58a = #58a58a
#969 = #969969
it's a shorthand way of implementing colors designed to save time typing.

Thanks for the links. However, I am still not clear about your explanation of #969 = #969969 I had thought that the six digit code had every 2 digits for RGB color ie R would be 96, G 99 and B 69?
Therefore, a handy tool where I input the 3 digit Hex code and it ouputs the equivalent 6 digit Hex code - is such a tool available?

 

Where did this come from? Each digit in a three-digit form is simply replicated to get the six-digit form.

#58a = #5588aa
#969 = #996699

Hey, it was early in the morning.

That's what I meant.

I personally use ColorZilla which is a built in FireFox plugin that offers the user to pick any color and get the hex, and RGB. Just google: FireFox ColorZilla PLugin
That should do what you need it to do.
