Could it be possible to change the color of words between parentheses?

For example, in:

"mejorar su bienestar psicológico (Cronin et al., 2012; Molero, Fuster, 
Jetten y Moriano, 2011; Outten, Schmitt, García y Branscombe, 2009; 
Pérez-Garín et al., 2016)."

I would like that this part changes into a lighter color, so it doesn't 
distract me when reading:

"(Cronin et al., 2012; Molero, Fuster, Jetten y Moriano, 2011; Outten, 
Schmitt, García y Branscombe, 2009; Pérez-Garín et al., 2016)"


Best regards
