Whatever is good in interior decoration is the result of consistent relationship between Light, Color, Form, Proportion and Dimensions. The choice of Color should be guided by the conditions of Light. The beauty of Form and the symmetry of Proportion can exist only by a balance with Dimensions. Therefore, apart from any knowledge of historic or period decoration, effective or successful work must observe the technical laws governing conditions. | Color Value By C. R.

The white light of the sun is compounded of an almost innumerable number of color elements as shown by the phenomena of the rainbow or by experimenting with the prism. See 5L_7. When a ray of sunshine passes through a glass prism it is decomposed or separated and if the prismatic colors are received upon a white screen you will find on the spectrum among the colors generated a pure blue a pure red and a pure yellow. These are the primary colors and it is necessary when thinking color to bear these prismatic colors in mind as standards. 2. Color is an internal sensation originating in the excitation of the optic nerve by a wave action which we call light. 3. The theory of light the wave theory is based upon the assumption that throughout all space there is an infinitely thin medium called ether. Scientists differ as to what this may be but its movements constitute light a reflection from a luminous body. 4. Everything which we see is visible because it either emits light like a flame or reflects light. 5. A piece of black cloth upon a white plate reflects but a small proportion of the light. The plate reflects a large proportion. A piece of black velvet reflects less light than black cloth and gives the effect of absolute blackness or an empty and dark space. 6.
