how to make the output stop outputting when it is a precise rgb number

Question

I am a beginner using python so there are probably gonna be a lot of stupid errors. basically i'm trying to do a png reader that prints the rgb value of every pixel of the png, and "filter" the rgb color "85, 115, 184". Idk what i'm doing wrong. Thanks in advance

from PIL import Image

im = Image.open('x.png', 'r')

pix_val = list(im.getdata())
if condition:
pix_val != (85, 115, 184),
print (pix_val)
return
else:
pix_val = (85, 115, 184),
break
