Hi
For this reason, attention should be given to colour schemes when decorating places such as offices and hospitals.
It seems as your topic,but it is not. I do suggest yo you avoid narrowing of your topic in the intro. Anyway your intro is great.
Furthermore, during working days people normally prefer to be in solid colour formal attire, whereas, in parties people usually like to wear high contrast dress which is well known for creating celebration mood.
Try to separate each idea into separate paragraph. If you have a number of ideas you have to mention it in your topic sentence of this paragraph.
Therefore
Do not overuse connection words,like this one.
Overall your essay is really good,however i would recommend to you focus on every words in the question.
The word "feeling" is ,i believe, different from mind,and so you might add information about how colours impact on feeling instead of mind.
Good luck
