Objects that appear blue reflect shorter wavelengths of light, while objects that appear yellow reflect longer wavelengths. This difference in reflected light wavelengths creates the perception of different colors to our eyes. Reflecting shorter wavelengths results in the perception of blue, while reflecting longer wavelengths results in the perception of yellow.
Objects that appear blue absorb longer wavelengths of light and reflect shorter, blue wavelengths. This is due to the molecular structure of the object, which selectively absorbs and reflects light. In contrast, objects that appear yellow absorb shorter, blue wavelengths and reflect longer, yellow wavelengths, resulting in the perception of the color yellow.
Objects appear to have certain colors because they reflect or absorb certain wavelengths of light. The color we perceive is the result of the wavelengths of light that are reflected back to our eyes. For example, an object appears red because it reflects red wavelengths of light and absorbs other wavelengths.

Mirrors and other objects reflect light, though most objects absorb some wave lengths and reflect others and black absorbs all wavelengths and white reflects all wavelengths.
Objects have color because they absorb and reflect certain wavelengths of light. The color of an object is determined by the wavelengths of light that it reflects, which are then interpreted by our eyes and brain as specific colors.
Objects with higher temperatures tend to radiate more strongly in shorter wavelengths. This is known as Wien's displacement law, which states that the peak wavelength of radiation emitted by an object is inversely proportional to its temperature. Therefore, objects with higher temperatures will emit more of their radiation in shorter wavelengths.

Objects show different colors because of how they interact with light. The color of an object is determined by the wavelengths of light that are absorbed by the object's surface and the wavelengths that are reflected or transmitted. The colors we perceive are the result of the unique combination of wavelengths that are reflected back to our eyes.
Objects appear white when they reflect all visible wavelengths of light equally, resulting in a combination of all colors that our eyes perceive as white. White objects do not absorb any specific wavelengths of light, making them appear colorless.
