Problem
I am now updating my CV and I want to replace the ugly block outside the hyperlink with the customized color. I read and tried the solution provided in these answers and websites (anwser1, answer2 help specify appearance of \href and website provide a long list of colors I could use) but I am facing three issues
After defining color as per the website, I use the customized color in
\MYhref, but the output seems to be pale all the time.In the two solutions,
\hrefis configured withurlcolor,citecolor, etc. However, I do not understand how the system knows the input format and determine the corresponding color (maybe regular expressions?). At the same time, I could not use the customized color here. It turns out to be pale all the time no matter what color I use.- I really like the color shown in this CV snapshot, but how do I know the parameters (RGB values) and use it in my CV?
EDIT:
Here is an MWE and resulting output. Note this example requires res.cls, which could be downloaded here.

\definecolor{myblue}{RGB}{33,22,92}, I think. There exist applications calledcolor pickerand so on which allow you to pick a color. – Feb 04 '19 at 01:36
