# Math Help - Colouring equations written using latex.

1. ## Colouring equations written using latex.

Hi everyone,

One of the things I have notice after the upgrade of MHF is that I cannot colour equations written using latex. For example the {\colour{red}xxxx} command does not seem to work now. Does anybody know how to do this?

2. ## I hope this helps

I don't, but you can study this tutorial: http://tex.loria.fr/graph-pack/grf/grf.pdf

Dear wonderboy1953,

I think you misunderstood my question. I wanted to know how to colour mathematical equations embedded in MHF. Before the upgrade of MHF it could be done by wrapping the text by {\color{red}{text}}. But since the upgrade this is not working. (look at the source code of the equation below)

$\int_{a}^{b}=g({\color{red}x})$

After the upgrade, we lost the TeX colour option, period.

In fact, that is just one of the ways in which the upgrade was actually a downgrade.

6. Is there a chance we can get it back?

I wish it will be a great thing if we could get it back because it is a valuable tool, specially when you want to highlight something (ex: mistakes in other posts).

As I understand it, there's no chance of getting vBulletin version 3 back again, becuase it had a security loophole that had been exploited. It would be nice if some of the good v.3 features could be installed on v.4, but I guess that would require a lot of effort from our overworked Administrators.

In that case we will have to resort ourselves to something else that would be good enough to highlight certain sections of equations. One of the things I have noticed is that you can use \boxed{....} command inside the equation mode and box any part of an equation. Hope it will be useful.

$\int_{a}^{b}~\boxed{x~\sin{x}}~dx$
