"Yellowy" rendering tone? what do I need to adjust?

[rob2218]

if you notice on the bottom rendering, the combed stucco is more "grey" where the top rendering for some reason, the tone of the combed stucco is more "yellowy".
I while back someone helped me out and said it was something to the do with the "sun" setting in the Cinemax rendering parameters.
What is it that I have to adjust so that yellow sunnish color doesn't over power the rendering?

You'll need to tell your client to chill out, as there is no accurate color other than in a laboratory setting. All is perception and affected by the ambient lighting, whether artificial or natural. For outdoors, the perceived color of any object changes at every hour of every day and with the weather and surrounding environment.

Just point the client to the image-gone-wild from a year or two ago of the woman in the gold and blue - or was it white and black - dress that took over the internet and talk shows. Our eyes need context to determine (guess) what is true white or black and calibrate from there.

Our eyes are also easily tricked. If you have a USA flag, for example, that the viewer expects to be pure red, white and blue but actually color it slightly differently - it will affect the viewer's perception of all other colors in the image.

Explain to the client that there is a reason that paint stores such as Sherwin Williams have 'light boxes' for you to put color chips in and view them under different lighting conditions - where the color chip looks different in every light box. No one light is 'correct' - just approximating the customer's anticipated environment.

Good luck. Clients who want things like this are probably impossible to please.

You nailed it sir.
thats an understatement for this guy.
he fusses over such little things that don't allow the production to more forward. I'm talkin' stuff like, moving a outlet centered with a door key hole or something as ridiculous as that....it's very odd the things folks tend to obsess over at times. God forbid you point that out to them and the all of sudden freak out.....and feel threatened of sorts....very odd.

Sigh. We all have clients like these sometime or the other. Doesn't usually end well, in my experience.

Thank goodness for the white model option in CineRender. I've started showing those at the initial stage and it's made a huge difference. For a change they actually look at the form instead of starting a pointless, detailed, discussion on the materials we're eventually going to use!

A bit off-topic, but a tip in general, once you tweaked things to work: save the settings as a scene, you can import that for a next project and perhaps most importantly, different views ask for different settings, so you might lose your hard found tweaked parameters for another render in the same project.

Oh, and maybe check your sun settings from Perspective > More Sun. I've got all of the colours set to white there, to make sure there is nothing else affecting colours.
