As usual, you are seeing intuitively the factors involved here. Karma will influence perceptions, attitudes, feelings, and the assessment of one's life experience and its meaning because it is a profound multifactor influence that can include a quite complex and nuanced energetic interchange that will have an impact. This is often amplified and distorted through outside manipulations via the Extraterrestrial Alliance wanting to impose their own influence on things. This they do again and again and again. They can introduce and support fashion trends in addition to artistic and architectural choices. Virtually anything about human society can be manipulated, particularly through influencing leaders and trendsetters, those in authority to make decisions about such matters as policies, and things related to imagery and the cosmetics in creating a workspace or even a personal living environment.
That is the case here with this cycle you have seen. Being malevolent, the extraterrestrials always are wanting to squeeze love out of the picture, because they know it hurts people, and will try to instill anything that is dull and depressing and denies happiness and positive emotions to be felt, generated, and shared. That is why this trend, as you rightly perceive, is sinister, because on its face it is clearly life-denying to paint the environment with a ghostly pallor more suited to a corpse than a thriving, bubbling, and joyous existence. It is a testament to human spirituality and initiative, that eventually people will so tire of this gloomy pallor they will begin to yearn more and more for the colors to come back, and that demand will start to influence the opinion leaders through the feedback from customers and clients. After all, money talks, and if the demand is there and insisting on personal preferences above the major design themes those sources would like to decree, they will give in and take the money, and that will begin to break a trend, at least for a time.
But, as you have seen, that will only last so long and then the gray will return to gain dominance once again through manipulation by mind control, to make people complacent largely, more so than simply wanting that color. They will be programmed heavily to accept it and even see it as a positive if touring a new home, for example, and see that it has been redecorated with the current palette of gray tones, may well be pleased that it is up-to-date and will not think more deeply. They might begin to feel some regret later, living in that environment day after day after day, but that will have to develop over time as the subconscious programming to embrace the darker themes fades over time.
