Is the shadow goes against the sun or other way? Thank you.
Sorry, didn't notice this was your first picture post. Welcome to the forum!
As Peter said, the sky above you (not in the distant horizon) would influence the shadows. Shadows, in general, are bluish, not cyan-blue, but neutral blue or slightly magenta-blue. That's what the UV filters were for in the film days, among other things.
How you should correct that is a different matter though. Sometimes it goes "against the sun" (i.e., cool tones), sometimes "the other way" (i.e., warm), and sometimes neutral works best. Worth experimenting.
In the film days, I would sometimes take off my UV filter as I wanted to
accentuate the bluishness of the shadows. In digital days, I would sometimes apply different white balance to different part of the image (e.g. one for the sky, the other for the foreground).
