I have always followed the UK English style in my poems. Colourful is correct as I have typed it above in UK English. In US English the "u" is absent and it becomes "colorful"...nothing negative intended here...just pointing it out to those who accuse me of misspelling certain words. I hope that I have clarified the point as lucidly as possible in this comment...Wishing all good fellow poets and poetesses the very best.
This poem is about two mystics who are destined to meet (In accordance with the Will of God Almighty and His fate writing angel/angels), very soon, at a place meant solely for incurable romantics with mystical tinges blending with their lust-free personalities...where light bursts into its seven fragments and composes a rainbow's song...smiles...
