Changing the main blog title's color

I've succesfully accomplished a change of colour in the blog's main title. In the teplate (plantilla, in spanish), in the first section entitled Header, I just added the colour code, without changing anything else. The command that I aded is here presented in bold charachters:

#blog-title {
margin:5px 5px 0;
padding:20px 20px .25em;
border:1px solid #222;
border-width:1px 1px 0;
font-size:200%;
line-height:1.2em;
color:#ff99ffccc;
text-transform:uppercase;
letter-spacing:.2em;

The reult is a bright pink colour for the blog's name (it's a long story), but it might work with other colours.

The following is the report of the different attempts I mede before getting to the previous solution:

Let's try now to change the colour in the very blog's name. I've found just three colour codes for html edition, so I will now try to meke the title green. In the Option tag, in the firt sub-tag, wich is basic, let's put the colour code for green in the following way: ... and see what happens

It doesn't work, I got the folloing message (sorry, it's in Spanish):
Su HTML no es aceptable: Tag is not allowed:

I will try now putting just:
Same result

I've now tried with different combinations with the color commands, same results every time.

I don't know if html codes are allowed in the main title. I will try this time with a break (which is the command I seem to have already mastered...).

The
command works,, so it must be about correctly entering the colour code. But, sadly, it seems that it doesn't work that way when it comes to colour.

Template Change

I decided to use here in "Das Experiment" the same template I use in my other blog... for cohesion and consistency, mostly.

The Title Color

In my main blog, I use the template called Minima Black. Which is fine by me in the overall, but I can't stand the neonish green color of the posts' titles. The problem is, I don't know how to get white. The current color "code" it has now is the following:

color:#ad9

Which gives the above-mentioned green (and is, I've discovered, the same color that the hyperlinks turn to when hoovered). a7a is purple (the same of visited links), and 9ad is a pale blue (of hyperlinks in th right-side bar). Some other two-letter-and-one-number codes give other colours.
I've also discovered that when you enter a code that the system (html code or language, I guess) do not recognise, the font then changes to gray --the "generic" colour for the post body (in my template).

So, I hope this would be somehow understandable. If anyone knows further and wants to type some knowledge, please do.

The Post

This is, as its very name aproximatively tries to indicate, a poor experiment. I'm tired of having no html knowledge and thus being unable do do what I want with my blog. Right now I'm color obsessed. I'm sick of the hideous green tone of my main blog posts' titles. I ignore what will be the ultimate destiny of this experimental blog: if i'm going to keep the page or eventualy delete it. For now I'm going to use it solely with the purpouse of learning how to use basic html to change some details in blogs. If you have any tip or comment don't hesitate and share it. Hopefully this experiment will help more than one ignorant and/or unexperinced blog user. Thanx
