Never seen this before 🙂 Need to remember

It’s a safe way for customizing your theme

For static pages you have simple way to do this – just select Fullwidth Page template in Page Attributes meta box on Edit Page Screen.

For single post, blog pages and blog archives this process will be more difficult. 1st question in that case – what you planning do with sidebar? Move its below other content on page?

If you create and activate child theme for Duena, you can override this colors.
For example, to change red color about you say(its global color for links), you just need write in style.css in your child theme something like

a {
  color:#what_ever_you_want;
}

to change hover color (it also be color which can appear on click on some links) you need add to style.css in your child theme

a:hover,
a:focus {
  color:#what_ever_you_want;
}

This theme based on Bootstrap front-end framework. So some styles placed in bootstrap.css (bootstrap/css/bootstrap.css)

Hi.
You need go to Apperance -> Editor in the Dashboard. Then open in Editor file standard.php.
Find there next code

if (has_excerpt()) {
 the_excerpt();
} else {
 echo duena_string_limit_words($excerpt,55);
}

you can replace string
echo duena_string_limit_words($excerpt,55);
with
the_content();
in that case you will have full post content if not filled Excerpt field under the post edit box and your custom excerpt if this field filled.
Or you can replace all code

if (has_excerpt()) {
 the_excerpt();
} else {
 echo duena_string_limit_words($excerpt,55);
}

with
the_content();
in that case you always will have full post content on blog page.
To disable “Read more” button you need to go to Appearance -> Theme Options -> Blog and find there option Enable read more button for blog posts?

Remember. Be careful with making changes in template files. Especially if you do not have much experience in WP templates editing

Hi.
You have the “Set Featured Image” link in the “Featured Image” box on the post editing page, when you set the Featured Image using this link for it will appear on Home page.
Don’t quite understand your 2nd question. what colors you need to change?
And about the 3rd question – I see you have Woocommerce plugin installed and i think this article can help you – http://docs.woothemes.com/document/product-variations/
