This color cover the brackets. I don't want this.
How to remove the setting?
This comes from Editor>Color Scheme>General in your IDE Settings. The setting you are looking for is under Code and is called Matched Brace.
On the right you should see a couple different settings which will allow you to control the way the matched braces look. For example, to remove the lime green border you can uncheck the Effects checkbox.
In your case, I believe it's likely that you have the Foreground checkbox set and that the color is configured to match your background color.
I'd suggest playing around with the Matched Brace color settings until you find a style you like. Unfortunately, the preview shown in this section doesn't give you a good example of a matched brace will look like. So you'll have to Apply the setting, look at your code, and re-edit if you want to make changes.
Are there any best practices or guidelines regarding contrast between link colour on a webpage, and the regular text?
I know there are contrast guidelines that refer to text vs background colour, but I'm also wondering if there are guidelines about the minimum colour difference that should exist between plain text, and link text.
For example, my background is white (FFF), my text colour is black (000) and my link colour is green (007C41)
Edit:
I realize it's up to personal preference to some degree. However, while my eyes may be able to tell the difference between #000000 and #000001 (they can't, but just for argument's sake), other's won't be able to. What I'm wondering is if there are any accessibility guidelines regarding what the minimum colour difference should be.
The only guidelines I was ever taught about links is this:
Make it obvious that it is a link. Do not do anything that might trick a user to click on something they didn't want to click on.
Make it obvious that it is different than the other texts on the page because you do not want your users to miss out on a link they might have wanted to click on.
Years ago, I was taught that all links should be underlined. Obviously, many, including our beloved SO, do not do that. Many now favor that links are underlined only when hovered over.

Make sure you have a color blindness emulator plugin for your browser. Inability to distinguish variations in hue is a semi-common condition. What looks "different" to you might not be obvious with a certain type(s) of color blindness.
Once you've addressed color blindness, ensure that colors with popular meaning (red, yellow, green) are used in appropriate or neutral contexts. For example, a "Sign me up!" link probably shouldn't be red (danger, critical) unless it's very clear that it is part of a theme (e.g. all links are red). A "Delete" link probably should never be green.
It's worth being familiar with proper color compliments. Even if you have made a highly readable, usable site, people react differently to different colors. Some colors/color combinations simply "look" better than others, and often there is a simple mathematical reason.
There are a couple of guidelines that combine to cover that scenario:
Color is not used as the only visual means of conveying information,
indicating an action, prompting a response, or distinguishing a
visual element.
Contrast (Minimum): The visual presentation of text
and images of text has a contrast ratio of at least 4.5:1
A good article on webaim explains that:
So if you combine these two requirements, in order to be Level AA conformant, your page must have all of the following:
4.5:1 contrast between the non-link text color and the background.
4.5:1 contrast between the link text color and the background.
3:1 contrast between the link text color and the surrounding non-link text color.
In other words, your link color has to be significantly different from the background color AND the surrounding text color, which also has to be significantly different from the background colour.
Overall, the easiest thing is to use more than colour, e.g. an underline, outline, or bold text, in which case you only have to worry about contrast compared to the background, not the surrounding text.
Most important considerations have been covered above. In addition to those considerations, I lean away from underlining (except on hover) because I like the option of using underline to convey emphasis or other contextual information.
Our self-proclaimed Usability Guru Nielsen at one time loudly exclaimed that all links shalt be underlined forever no matter what, and a lot of people who prefer to be told instead of do the thinking themselves gobbled that up. But most reasonable designers understand that such rules are nonsense.
I am trying to make a text-based RPG. Someone said it might be too hard so i should make keywords different colours. F.eks There is a locked chest, when you examine it you see that some of the nails are loose. You can get the loose nail and open the chest with it.
How do i change the colour of just that one word? Or how do i make just that one word italic?
myTextField.htmlText = 'You can get the loose <font color="#ff0000">nail</font> and open the chest with it.'
If you use the textfield to display your text it accepts an htmlText input. Some (but not all) html formatting is acceptable there.
The TortoiseHg Commit window has a thin vertical red line in the text area where you can write your commit message:
What is the purpose and/or meaning of this line? The relevant TortoiseHg documentation comes up empty. Searching Google and Stack Overflow currently give zero results.
Is it a suggested(?) or recommended(?) place to put hard line breaks in commit messages? If so: why have such a suggestion at all, and why at that particular location?
Okay, bro, it 's your personal hand-made settings (default value - unspecified)!!!
TortoiseHG - Settings - Commit
and at the bottom, when this listbox is active, you can read description and purpose of this parameter
Without knowing this platform I would say it's a text wrap marker - where text would wrap when printed as pure text to a printer. the old "standard" had a width of 80 chars (72 on some platforms) for ASCII-based documents.
The width was also relevant to pure-text document viewers who typically wrapped text at 72 or 80 chars. It was also used for terminals at the time when BBS'es was the norm (before internet became popular).
I suspect the reason is to provide backward-compatibility to the more old-school developers who might want to read this in a plain text reader and for printing (printing pure text is many times faster than formatted text which is printed as graphics, and therefor convenient when printing documentation and so forth). But this will be just a guess on my part.
Never seen before that url bar would change its font, but if you go to the following link in Chrome, you would see that "New Features" is written in different font:
Copying url into text file reveals some magic symbols:
http://g-wiki.net/wiki/Battlefield_3%EF%BC%9ANew_Features
Can anyone explain why it changes font and what else can I do with this technique (can I make red bold letters)?
That's a full-width colon character. The only difference should be that it takes more horizontal space; it's not supposed to affect the font and it doesn't do so for me. However, because it's missing from many fonts, some operating systems might switch to a different font or rendering mode in order to display that character, and may continue to apply this change to subsequent text.
I've noticed this before in instant messaging. I'll copy some Chinese characters into my message, and the rest of it will be displayed differently. It's the same effect and I'd consider this to be a bug in the the operating system/font routines. It's probably not been deliberately programmed.
