How to remove color attributes alone in style attributes of HTML and at same time, not to remove color in HTML view content

Question

I want to remove 'color' attribute alone in style attributes of HTML and at same time, not to remove color in HTML view content.

Here, I provided the sample HTML.

Step 1: Defining regex for html codes range.

<(?:"[^"]*"['"]*|'[^']*'['"]*|[^'">])+>

If I use the above regex pattern expression to select HTML language codes then it selects the content within "<" and ">". Please refer the picture.selects only html code and not the HTML view content

<?xml version="1.0" ?>
<html
    xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta content="TX20_HTM 20.0.405.501" name="GENERATOR" />
        <title> well marked style="color:blue;"</title>
    </head>
    <body style="color:red;"> this is atest
</body>
  </html>

Step 2: Defining regex to remove color attributes from HTML coding.

But, within the html attribute contents I want to remove color alone. I have a regex expression to remove the color attributes.

(?i)((background-color|color)\:([a-zA-Z0-9#)])[a-zA-Z0-9.(),]+;*)

But, the above regex pattern also remove the color from HTML View content as well. Please refer the picture.

selects all color attributes

Actually, for my case, the color attributes should not be removed from the HTML View content.

Step 3: I want to mix the Step 1 and Step 2 regex

Basically, What I'm trying to mix up these two expressions but, it is not resulting the correct what I expect and I'm not familiar about these expressions..

Please suggest..

which the regex pattern can be used to achieve the above said requirement?

regexes are not the way to go, use an html/xml parser that supports xpath queries. — Casimir et Hippolyte, Jun 18 '18 at 08:39
Trying to parse HTML with a regex is a bad idea. See also https://stackoverflow.com/a/1732454/1848654. — melpomene, Jun 18 '18 at 08:55
we have limited size of content and hence we go for a regex parse. Any solution on this please? — Mari, Jun 25 '18 at 07:45
