Silly questions about the behaviour of photons

[QUOTE="victorhugo, post: 5448811, member: 566644"] Please bare with me as I haven't studied much at all about light in high school physics. When we see an object as red, does that mean the way that photons bounce off of it cause only light at the wavelength of 'red' to be reflected? If so, wouldn't that mean that the light reflecting off of a red object would be warmer than the light reflecting from a blue object(since red light with its higher wavelength warm things up more) And so, doesn't that mean that it would have less intensity since it's carrying the same amount of energy but as 'heat' instead? Also, we describe the electromagnetic spectrum (light) as having different wavelengths, but also describe it as photons which are 'energy packets', how does this work at all? Are photons the purest form of energy? Since they can never be still and only bounce off of electrons, they transform into heat and therefore disappear? Also, since heat is kinetic energy of particles, how do we see heat being radiated from objects? How does the kinetic energy of particles create electromagnetic waves (and therefore protons?) Is time described as another dimension or simply the flow that energy undergoes inside of 'space'? [/QUOTE]
