And...? I'm not sure what if anything you're trying to imply,
but if you change the shutter speed you won't have the same settings in auto that you had when everything is set to auto, that's not how a camera works.
Most everything changes, WB especially, ISO obviously and maybe even exposure compensation, all those will effect the color either a lot of just barley but they will. Also see how the camera is pointed down about 5 degrees in the top photo? on Auto WB will read more of the shadow than the bottom view and shadow is 'blue' and in order not to make the scene too blue the auto WB compensates and adds warmth = warmer color.
Auto mode is just trying to create the best color from what it sees, a few degrees lower can effect exposure a lot. If you see those pictures enlarged, the top picture is aimed lower than it looks like does in the smaller view above and with the few degrees more of blue that you get with blue shadow, it will effect exposure and more immediately the added yellow hue. I'm not surprised its warmer - I'm old school I know how a hand held meter works and a built in has to calculate all kinds of variables in auto mode and its never perfect. That's why the Pro Cam has so many manual overrides you just need to know how they effect a scene. Your adjustment is a perfect example, changing the shutter speed just didn't reduce camera movement and blur it effected all the other modes set to auto and the results is a picture not limited by the limits of auto everything. Auto is sophisticated guessing that's all and unless the light is neutral and shadow and light is evenly balanced in a scene auto is like auto pilot, it doesn't compare to manual and it's meant for known variables (simulated life) not real life. It can help, but knowing how the camera sees along with manual adjustments will create better pictures than auto everything
everytime if you're willing to learn.
