One thing I can clarify is regarding the color red.
When we do our visualization we should visualize ourself with a central channel. This central channel runs from the crown of our head to our heart. We should visualize our heart as a pink/white lotus. The red refers to the the inside of our central channel. The central channel is about the width of a straw and is red on the inside, and blue on the outside. The ball of light can be all the Buddha's dissolved into one, or it can also be Dorje Shugden dissolved with your Yidam or Guru. We visualize this ball of light entering our central channel and merging with our heart, which we see as a lotus. Then we see the light grow and exit through the pores of our skin as you said 'iloveds'.
This is just a basic clarification. I can go into more detail if needed, but there are so many different meditations it is hard to say which one you are doing. Im sure people will help to clarify your question more, as I do not entirely know what the gold represents.
