Survey theme/template:
==================
I am using version 6.10.0 on a contracted server
I have created a survey and I am using the bootswatch theme.
I have noticed that the warning messages that appear in the mandatory questions have a color very similar to the blue background that contains the question mentioned
Please, what should I do to change the color to one with greater contrast like a light gray or some other color?
Thank you

Hi, in such cases it's always the best to use the webdevelopment-tool of your browser (F12) to find out which classes are affected.
In this tool you can directly change values to see what fits best.
 
Then enter this either in the question text (source code mode)
or - better - in the custom.css of your extended theme (then without the <style>...</style> tags.

Thank you very much. You are the best
I use this code:

.question-valid-container.text-info {
color: yellow !important;
}

In custom.css
in extiende_bootswatch template
