Atticus shows this in the smallest of ways, such as with the family's ornery old neighbor, Mrs. Dubose, who makes a habit of taunting Jem and Scout when they walk by her house. Just hold your head high and be a gentleman, Atticus advises Jem.
As light continues to move though the atmosphere, yellow wavelengths are scattered leaving orange wavelengths. Further scattering of orange wavelengths leaves red as the predominate color of sunlight. Therefore, near sunrise and sunset, a cloud's color is what sunlight color it receives after Rayleigh scattering.
The colour of a cloud also depends on the colour of the light that illuminates it. When sunlight passes through thick layer of atmosphere and dust particles at sunset, blue colour is scattered by Rayleigh Scattering and only red-to-orange color remains (see Question 2). The clouds reflect these unscattered red/orange rays and appear in that colour (Figure 6).
