For the red widget, try (and so on)
[youlist search="+red -blue -green, @yourchannelname"]
(long version)
By the way YouTube constructs the iframe api you can only use the attributes uid, pid and search separately.
But perhaps you can achieve this by using the search attribute:
[youlist search="..."]
I think the YouTube search is checking:
title
description
category
tags
Here is one search query that you might find useful:
[youlist search="cool, @mismag822"]
It searches for videos where the name of the channel is mismag822
and contains the word cool
[youlist search="+cool -beginner, @mismag822"]
This query searches for videos where the name of the channel is mismag822 and contains the word cool but excludes the word beginner
To restrict the search to videos published last year:
[youlist search="+cool -beginner, @mismag822, last year"]
we can also use: today, this week, this month, this year,...
To search only for high definition videos:
[youlist search="+cool -beginner, @mismag822, last year, hd"]
Here are some other search keywords I could found:
hd, webm, last week, this week, cc, long, partner, creativecommons, live, playlist, music, movie
So in your case you could use something like
[youlist search="+red -blue -green, @yourchannelname"]
to use in the red widget and so on.
Hope this helps.
