Hyperlink colour?

Hyperlink colour?

To get a hyperlink in the colour I want, I select the text, choose the colour and then add the hyperlink. And it works!... sometimes. Some other times, the hyperlink colour just reverses to standard blue hyperlink colour.

Mails in I-pad seem to work, webmail also works, but some other mails... well sometimes it works and sometimes it doesn't, so that in the end, there could be two different hyperlink colours in the mail I send to customers. This is of course not satisfactory.

The problem is thus not CONSISTENT and I cannot nail it down, why it sometimes does and why it sometimes doesn't work - As I always use the same procedure, described at the beginning of this mail.

I have read of this problem in the forum, it was already spoken about 1 year ago, but I do not understand what could be the solution. The ones described don't apply.

Can anybody help?
