Colour options for final piece

When concidering colours to use in my final, I had a few options, I could use earthy green and blue tones to represent nature and life, or contrast this by using rusted brown tones representing the decay and destruction.
 First I felt the rusted tones would go well with my concept of addiction, as its still thought of as a taboo subject. By using the hints of red, it gives the imagry of danger, something to be avoided and not discussed. I added highlights of grey to emphasise the cells made by the acrylic and also to represent cold metal, which can be seen as unforgiving and shows the stages of metal rustings, from shiny silver to the rough orange and brown brassy tones once the metal has been broken down. This reflects ones mental and phsycial health after becoming addicted to a substance or drug.

 Contrasting this, I did several experiments on large canvases also exploring using brighter, more primary tones to see how they'd complent eachother. For this pour I used green and blue with highlights of yellow to catch the eye and highlight the cells, and break up the similar blue and green tones. Using a pipette I added more spots of yellow which I feel look like cells growing in a culture, and also used syringes to squirt patches of red acrylic throughout the piece. By using syringes I've linked back to my concept of using drugs and addiction, and the red colour represents the blood but can also represent danger and frustration of becoming addicted and chemically dependant.
Upon reflection, I feel the rusty tones would complement the background of the metal circles more, as they both will posess the metallic texture.
