At least one of these interpretations must be true (1 or 2). The authors try to demonstrate the only possible questionable reality is only one of the two realities. Whilst the authors attempt to propose answers to the question, both pathways are possible. Interpretation 1 indicates that the world has the same colour as in our minds while Interpretation 2 justifies that colour is relative and cannot be determined. It also implies new knowledge, which is difficult to be accepted. Readers have the choices to choose. Nevertheless, at the end of the day, readers will have to choose one of the options available (no choice). Interpretation 1 or 2; the reality is then derived from the chosen one.

What happen in the main source of light? The conversion of energy occurs in a nuclear fusion process in the sun, which is the conversion of Hydrogen to Helium. Besides other energies, the sun releases the main energy, known as an Electromagnetic Wave (EM), which is the source of the meaning ‘colour of nature’. Almost the entire EM spectrum affects objects on the earth. Leaves are green because of the photosynthesis process. They absorb most of the EM energy around 570nm and 440 nm, which indicates the interpretation of the human mind towards the colours red and blue respectively, whereas most of the EM energy around 540nm can penetrate the thin leaves (which appear to be green in colour if viewed from the bottom, whereas the thick leaves will look black in colour if viewed from the bottom due to the all related frequencies (green) that are reflected back). The frequency’s energy that is equivalent to the need or absorptions of the material will be absorbed by an object (like an accurate radio station frequency receiver). Therefore, each of the returned energy is equivalent to the least or most unwanted ‘colour’ energy. The reflection of GREEN EM, which is less needed is certain. However, it is uncertain whether the colour of the leaf itself is really ‘GREEN’? Whereas, On Planet X, if leaf X’s photosynthesis process absorbs all EM energy of medium and low frequencies, the leaf will appear to be in blue- violet colour. Do the leaves have an actual GREEN or BLUE-VIOLET colour? Is colour characterised as the OBJECTIVE (Interpretation 1) or RELATIVE (Interpretation 2)?
