Yes! The surface reflects light it scoops up from the visible hemisphere around it. If some of the hemisphere is sky, then the light cast onto that surface will be tinted blue. I'm not sure if people have access to it, but here's an example from an airborne imaging spectrometer that is flying over a partially-shadowed domed building (on the Caltech campus): https://www.sciencedirect.com/science/article/pii/S0034425723000482 https://www.sciencedirect.com/science/article/pii/S003442572... Figure 4 shows the dome (really a cone) - note the shadow at top-right. And figure 5, panel C, shows the contrast-enhanced light reflecting off that dome. You can see that the shadowed portion in the upper-right of the dome is bluer than the directly-lit stuff. (The directly-lit stuff is more golden, from the direct sunlight.)
