Is a phrase that has no meaning. In much the same way that the color of 9 has little meaning, we often use phrases and expressions that do not reflect reality.
Take for example the time of purple. Time is a function of process. A process is simply the movement from one stage of existence to another. We perceive time in movement - because movement is an expression of movement over a particular distance - i.e. change. That change can be constant (i.e. 0 acceleration), or can increase. However, the fact that there is speed over some distance indicates that time has been traversed. Purple is a property of objects. Time is not an object, but an expression of a change in process, it, by definition is not an object of which we can attach a property of purple to it, and so the meaning of time of purple is utterly ridiculous.
Take for example the number "9". Abstractly, 9 is an integer, and can have certain mathematical properties. If I have 9 pencils, that means I have 9 individual components that make up a set of 9 pencils. The pencils can be purple, but not the number. The number does not have a property of how it looks or is perceived in the world. It is an abstract concept to relate to the world on a mathematical level. To speak of 9 having the color purple is not relevant.
These two examples show that our value and attribution to objects, things, abstract ideas, concepts must be logical and correct. We cannot assign color to an abstract idea. Only objects - physical entities can reflect the photons of light that produces the appearance of color.
We must be very careful when we assign a property to a being, object or abstract idea. Can such an idea, or object have this property attached to it? How do we know? Is it provable or justifiable? If not we are merely ascribing the color purple to time, which is a Purple Fallacy.
