The main chakras, energy centers, follow your midline and are associated with different psychological and physiological aspects. They have color associations that typically match the colors of the rainbow, and you remember the order by the old kindergarten mnemonic ROY G BIV, a person who is our friend. ;)
People talk about chakras being wheels, like cogs. Others talk about them being cones with the 2-6 having a back and front cone. I tend to see them as spheres, and I tend to see the spaces between and the full connective column from deep earth to the heavens as a DNA strand. Some people see slightly different colors. I know one person who sees the the Third Eye chakra as magenta, and many people saw the crown chakra as clear or white.
There are different aspects to each chakra, how you support that chakra and what you project for others to see, or. Some people believe that root and crown don't have these aspects, but I disagree. You can project being spiritually connected and being "high vibe" but are actually a creep taking advantage of people, and you can project being very grounded but really you're falling apart inside.
In other words, every chakra needs your care and attention, just as every aspect of yourself does. Every chakra may need strengthening, or may simply have the message that need to tell you that you're good because, you know, we get used to thinking we are doing terribly, even if we're not. ;)
One more aspect I feel should be mentioned here, the spaces between these chakras are just as important as the chakras themselves. If you learn that emotions and power don't go together, such as if a parent is always "disciplining" you in anger you learn that to be angry and to be powerful is bad. Then you put a block between those two chakras which interrupt flow and other chakras try to make up for it in other ways. If you find these details on the spaces between them that I provide overwhelming or confusing, just ignore them and focus on good communication between the chakras.

*Erik Erikkson's stages of human development. The theory has things happen in a specific order, however, in reality, these things can happen out of order, and in many instances happen concurrently. It is the same with other aspects of energetic, spiritual, and physical development.
**upper and lower is NOT a judgement. One is not better than the other. All are needed to create the rainbow. All are needed to create white light, for unification and oneness. There is Lower Dantian, Middle, and Upper. I sometimes also think of them as Land, Sea, and Sky, but that's my Celtic roots showing.
