Creativity with Jomsocial botton color

Hi, here comes an other simple question.
As you can see at the picture the 'cancle botton' if quite bad to read (white on light grey).
How can ein Change the Color of this botton in the template?

Many thanks Marc.

Could you please post an url to your site - to a place where this buttons can be seen?

HI it's a bit difficult to put it online at the Moment. Therefore I took some Pictures. I'm a real NEWBIE - so pls forgive me my questions.
Where do I've to write what to change the colour from light grey to a darker colour at the creativity template. But by the way I've the same question for the #gktop at the MSocial template. Because It’s standard colours are better readable.

PLs do me a favour and write a word more that I could understand put what where.

Many thanks upfront Marc

Without access to an online site I can't help much more.
Please write back as soon as the site will be online.
