Yellow in the Spirit

Lately I have wanted to figure out what yellow means in the spirit. So I looked in one of the reference books I have for symbolism defined by verses in the bible. The closest color I could find was amber. The book stated that amber means; The glory of God. I pressed more into the spirit and saw that along with The glory of God yellow also means royalty, rejuvenation, and strength. Also resistance in a good way I saw one of those stretchy bands that you work out with and pull. This means when you see yellow it may mean a divine test and endurance.
