Color changing

[TaraBNeri]

Im having trouble trying to change the color of the blue pillars.. I want to change the color to a off white or very light green. Right now I am using the color replacement tool I chose the light blue and I get a darker green color and if I switch to white I get a grey. I know its because of the orignal blue but dont know how to fix that.. ive also expierimented with the hue/saturation adjustment layer and still cat get the look im going for

Hi

That’s going to be super hard because the lightness of a white or off white column is entirely different to a dark blue. 

Really switching colour on an image needs to be between similar density values to succeed.

Maybe you can photograph some white columns with similar ambient light conditions and composite them into the original - that's what I'd do.

I hope this helps

if so, please "like" my reply and if you're OK now, please mark it as "correct", so that others who have similar issues can see the solution

thanks

Chanel mixer layer.
BlendMode Ligthen.
Red (+100,0,0)
Green (-100, + 100, + 100)
Blue (0,0, + 100)
Duplicate the layer three times.
Make StampVisible (new layer, ctrl + alt + shift + e)
Use ColorReplacement to make green white.
