It is because they reflect certain wavelengths (colors) of light more readily than others. White light contains all wavelengths of light. You can see this by passing the light through a prism or by observing a rainbow. Now, if you have an object such as an orange and shine white light on it. The red and yellow will be reflected and the other colors will be absorbed. Thus, we see an orange object. Now, if you shined pure blue light on the orange it would look black, because there would be no red or yellow to reflect.

Do objects absorb water?
Yes, objects can absorb water if they are porous or have spaces within their structure for water to seep into. Materials like sponge, cotton, and paper are examples of objects that can absorb water.
Why does white dries faster than black?
White objects reflect more light and heat compared to black objects, which absorb heat. As a result, white objects do not retain heat as much as black objects, leading to quicker evaporation of moisture and faster drying.
What is the purpose of using coloured alcohol instead of using any other compound in thermometres?
Coloured alcohol, such as dyed ethyl alcohol, is used in thermometers because it has a lower freezing point and a wider temperature range compared to water-based solutions. This allows for accurate temperature measurements over a wide range of temperatures. Additionally, the color makes it easier to read and interpret the temperature on the scale.
Are natural coloured objects better heat conductors than artificial coloured objects?
No. Heat conduction has little to do with color.
