Gmail styles link as blue and underlined by default

#1155CC is the default colour for Gmail links. You can overwrite this colour using inline CSS. However, Gmail ignores #000, #000000, and “black” values. For example:
This will render as red:
<a href=“http://www.emailonacid.com” style=“color:#C00”>test</a>
This will be rendered as the default (#1155CC) colour:
<a href=“http://www.emailonacid.com” style=“color:#000000”>test</a>
To fix this use a different hex value that is close to black:
<a href=“http://www.emailonacid.com” style=“color:#040400”>test</a>
Underline
Links in Gmail are also underlined by default. You can overwrite this style using inline CSS.
For example:
This will render with an underline:
<a href=“http://www.emailonacid.com”>test</a>
This will render without an underline:
<a href=“http://www.emailonacid.com” style="text-decoration:none">test</a>
