Conclusion

 

As I fade back to grey.

Well, not precisely, but I will not be keeping the contacts. Not because of the price but because I don't find them effective enough and they make me too tired and colour-dazed. Its been a fantastic journey. I don't expect other than colour blind persons to understand, and probably only colour blind artists could fully appreciate the experience. And there is not many of those around. That's about all on this experiment.
We'll see how research develops and when it's a good time to try this again. Cheerio.
