Change size and colour of body copy below posts on blog page

I want to change the body copy font size and colour on my blog page . I've successfully changed the H2 and the link colour, but I can't figure out how to target the body copy. This is the code I'm using. I think I'm not picking up the right class but I can't figure it out. Can you help?

/* Smaller H2 and body fonts and coloured links on blog archive page */
h2.entry-title {
font-size: 20px;
color: #141414;
}

p.entry-summary {
font-size: 16px;
color: #04edbb;
}

a.read-more {
color: #f988a9;
}
