Blue. That's why people call it a "blue surface" ... because any other color of
light that hits it is absorbed, and never scattered or reflected to your eye.
When blue light is shone on a white surface, the surface reflects the blue light while absorbing other colors present in the light spectrum. This selective reflection results in the perception of the white color.
Any object that has light shone on it would appear in a particular color because the said object absorbs all the other colors of the spectrum and reflects one single color. when the light itself consists of a single color, the color of the object gets modified because the reflected light contains the color of the light and then part that is reflected. For ex, the wall in the question would appear red if the light is only one wavelength but would appear as a combination of red and its own natural color if the light is a combination of different wavelengths.
A blue surface reflects blue light. This is because it absorbs most other colors of light in the visible spectrum and reflects only blue light back to our eyes.
When a ray of light is shone at a mirror, it will be reflected following the law of reflection, where the angle of incidence is equal to the angle of reflection. The reflection will produce a mirror image of the object or light source.
The blue sky would appear green under green light because the green light would dominate the color seen by our eyes. The color of the sky is determined by the light that is reflected off of it, so when green light is shone on a blue sky, the green light will be the dominant color that is reflected.

It reflects back and a small amount is absorbed into its reflective surface.

When a yellow ball is illuminated with magenta light, the magenta light is absorbed by the ball's surface. The remaining light that is reflected and reaches our eyes appears red because red is the complementary color of green, which is what yellow and magenta combined create. This phenomenon is known as color subtraction, where certain colors are absorbed and the remaining colors that are reflected create a different perceived color.
Because white light is made up of all the colors of the spectrum, and an object that appears red in color is simply reflecting the color red, a white object refects all the colors of the spectrum while black objects reflect no colors at all.
A red light shined on a red surface will be mostly reflected, as red surfaces tend to reflect red light and absorb other colors. The surface may also absorb a small amount of the light, depending on its material properties.
it will reflect off it
No, your shadow cannot be reflected in a mirror. A mirror can only reflect light that is directly shone on it, whereas a shadow is an absence of light being cast by an object blocking light sources.
When white light shines on red ink dried on a glass plate, the reflected color will be red. This is because the red ink absorbs all other colors in the white light spectrum and reflects only the red light, giving it its red appearance.
