Hi Paul. Here is my perspective:
Things of such nature such as seeing colors, or other things we may see: ghosts, dark figures, interesting sounds, voices in the head, beings/entities, etc...
are not alone trustworthy. Because alone they are of the Mind, and nothing of the Mind alone can be trusted. What can be trusted is the Physical and so cross-referencing with the physical. Anything that cannot be cross-referenced with the physical is immediately irrelevant.
In this particular case you are relating colors in your mind to self-experiences. So you don't need colors to tell you what your self-experience is. You can work on developing your self-awareness of what you are experiencing.
I highly suggest walking the desteni process, because if you do you can immediately start doing the self-forgiveness on all the mind points. You can forgive for thinking, and participating in the mind and for any kind of reactions towards these experiences. You can immediately stop the emotions like bored or blank or low energy through the Self-forgiveness statements and then MOVE yourself and DIRECT yourself in the physical. Doing this process you become a self-willed being with nothing going in your mind and you are being practical and proactive in your day. This is a process, and takes time so be gentle with yourself.
I highly suggest signing up with the courses and to do your self-forgiveness application regularly and to read the self-forgiveness of others. Seeing colors to know your own experience is redundant and it does use Mental energy to create the pictures. So I would do self-forgiveness on the point and see how it goes. You can share your findings here and we can respond. Though focus on stopping the mind points as best you can, so you can see the results.
The mind feeds off of the physical, so stopping the mind points will alleviate stress on your body.
