When you hold a piece of paper up to sunlight it looks white. But when we look at the Sun it looks yellow. Who's first with the answer?

But isn't lamda max for 5800 K in between yellow and green? And due to scattering and also that our eyes are more sensitive to yellow, that we then perceive the sun as yellow?
And to answer the original question, you are seeing light shinig through the paper.
P.S. Tyger we are waiting for you to go on the physics Q&A game
The sun appears yellow because of its temperature. The surface of the sun has a temperature of about 5,500 degrees Celsius, which emits light in the visible spectrum. This light appears yellow to our eyes.
Paper appears white because it reflects all visible light wavelengths equally. This means that the light that hits the paper is not absorbed, but instead bounces off and reaches our eyes, making the paper appear white.
Although the sun's light contains all visible wavelengths, our atmosphere scatters the shorter blue wavelengths more than the longer red wavelengths. This makes the sun appear more yellow to our eyes, especially when it is lower on the horizon.
Yes, the color of the sun is determined by its temperature and the composition of its atmosphere. The high temperature of the sun's surface emits yellow light, and the scattering of light in our atmosphere makes it appear more yellow than other colors.
The color of the sun may appear to change throughout the day due to the angle of the sun's light passing through the atmosphere. It also appears more yellow during sunrise and sunset due to the longer path the sunlight has to travel through the atmosphere. However, the sun's actual color remains the same.
