How to change the font color - not enough contrast

Members complain that the font is too small and the light grey color on the white background does not provide enough to contrast making it difficult to read.  I don't find the color pallet icon on the edit feature. This especially true on the Meet our Members page

Can you be specific on what page are you seeing a light grey on white?

Look here: 28676894.toastmastersclubs.org/meet-our-members/

And thanks for all that you do!

I am looking at the page you suggested and It looks good on my monitor,
Can I ask what monitor they are viewing the page on?
What OS are they using and what Browser.

Are your members aware of the browser tools like 

• Ctrl + + → increase text/page size
• Ctrl + - → decrease text/page size
• Ctrl + 0 → reset to default size

I got on a Windows box with a regular monitor and saw what they meant. 
The text is a little larger and darker now.
