Can’t change the title color

Hello,

I’m using the plugin to filter blog post. I have the following code:
[AWL-BlogFilter blog_image=”yes” blog_image_hover_effect=”hover1″ blog_title=”yes” blog_title_color=”#000000″ blog_desc=”no” blog_desc_words=”0″ blog_read_more=”yes” blog_read_more_text=”Regarder” blog_date=”yes” blog_date_color=”#000000″ blog_pagination=”yes” blog_buttons_color=”#000000″ selected_categories=”5″ custom-css=”” ]

DOing this, I have my titles that are invisible because they are of the same color as the background of the tile. I’ve tried an HEX code as color of the parameter Blog_title_color but nothing is changing…

What should I do?
Thx!
