Sharpen Text?

Is there a way to sharpen the look of the text, specifically the body text? I’m not talking about the change of fonts, what I’m talking about is the sharpness of the text? For instance, I could use a font on your theme and on another theme, and on another theme that same font color (for instance black) would look sharper, deeper and jump off the page more - but on your theme it would look lighter and more subdued. So I just want to adjust the sharpness to the degree that I’m looking for.
Hope you understand what I’m trying to say.

Hello there,

Thank you for asking.

By default, the body color is #767676. You could change it through Appearance > Customize > Color > Body text.
