what colour is an orange?

orange

The wavelength of visible light is in the range of 400 to 700 nanometers (nm) from Blue to Red colour

Orange light has a wavelength of 620 nm

Therefore an Orange should have a colour whose wavelength falls within 620 nm +/- 20nm.

Red + Yellow in proportionate mixing if you mean colour

combination.

If it is fruit, then the colour itself orange.

The color of the objects which we see are largely due to the way those objects interact with light and ultimately reflect or transmit it to our eyes. The color of an object is not actually within the object itself; rather, the color is in the light which shines upon it and is ultimately reflected or transmitted to our eyes. An object absorbs the colors that are the same and reflects the rest of the light for us to see. So, to answer your question an orange is every color except orange.

orange is orange . to make orange you mix 1 part red. 2 parts yellow.

Orange is the name and it is reddish yellow. The combination of red and yellow change at various levels and make a variety of shades.

occurs between red and yellow in the visible spectrum at a wavelength of about 585–620 nanometres.

Orange you clever to ask that question?

orange.
