How color vision actually works is still a mystery, but there is no mystery about the profound effect color has on human physiology. Red tends to raise blood pressure, increase pulse rate, and excite brain waves. Blue tends to have the reverse effect, and green tends to be neutral.
So, if you are having writer’s block, try a little color therapy. It can’t hurt; at the very least it will give you something besides your computer screen or those same old walls to stare at. And it has the benefit of being exceedingly simple. All you have to do is choose your color from the following list, wear it, hang it on the wall, find a knickknack or a bouquet of flowers that color to put on your desk, then focus on it.
Purple will boost your creativity, and help stimulate your intuitive abilities.
Yellow can help you feel optimistic if your blockage is making you anxious and depressed. It can also induce enlightenment, which is what you are looking for.
Dark blue encourages meditative thinking, so it’s especially helpful if are having difficulty focusing.
Green helps promote harmony if your inability to write is making you irritable.
Red will energize you if you’re too tired to think.
Even if the color therapy doesn’t bring about the effect you wish, playing around with all those colors will give your mind a rest from writing, and perhaps when you return to your keyboard, the problem will have resolved itself.
If not, do what I do: go for a walk.
