The blue surface absorbs most colors of white light except for blue, which is reflected. This reflected blue light is what we perceive with our eyes as the color blue.
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.
When red light and blue light are both projected onto a white surface, they combine to create magenta light. Magenta light is a different color from red or blue, which is why we don't see red or blue individually in that situation.
When white light passes through a blue filter, the filter absorbs most of the colors in the white light spectrum and only allows blue light to pass through. As a result, the white light will appear blue after passing through the filter.
The paper appears dark because red light is absorbed by the blue pigment, not reflected. The blue pigment absorbs red light and reflects blue light, which is why the paper appears blue under white light.
It absorbs all colors in the white light, except for the blue, which it reflects and scatters, and it winds up appearing blue to our eyes. That's a big part of the reason why we call it "a blue box".

The light from the sun, which is made up of equal parts of red, green and blue (even though it may not look it), will be reflected off of the white surface, staying white as the white surface reflects equal parts of red, green and blue.
When red light and blue light are both projected onto a white surface, they combine to create magenta light. Magenta light is a different color from red or blue, which is why we don't see red or blue individually in that situation.

Depends on the colour of the light, but with general white light, which is made up of many colours, the blue block absorbs all colours in the white light, apart from blue, which is reflected off the block into our eye, which is why the blue block appears blue to our eyes.
You get light blue.

Light blue and white make a pastel blue color. Mixing white with light blue lightens the shade and creates a softer, more muted tone.
Red and blue lights shining onto a white surface together would show as magenta.
Depending on the range of wavelengths that comprise the incident light, some of it may be absorbed and some may be reflected. If blue wavelengths are present in the incident light, then the blue is mostly reflected, and any other wavelengths are mostly absorbed. This is the main reason that the surface acquires the reputation of being 'blue'.
If you separate "white" light in a prism, you get the visible spectrum, (ROYGBIV). If you get that back together, you get "white" light. If you mix red and blue, you get purple, and so on.
