How can I change the font colour of the field titles?

For instance, I have named fields with 4 options.  If I go into the Designer and change the font colour the colour changes for the options but not the field title.

Can you please tell me the solution? 

regards,

Marg

Kindly use the following CSS in your designer

#label_8, #label_10, #label_12, #label_14, #label_16, #label_18, #label_20, #label_22 {
    color : blue;
}

It targets the titles using their ID since using classes will change every color including the ones on the text boxes,

Please let us know if you need any clarification
