You can use ColorDrawable to create a color for each item, according to its color, and assign it as the item view's background. To get a color between two colors with a percentage, you can use ArgbEvaluator:

int color = new ArgbEvaluator().evaluate(getAdapterPosition()/365f, Color.GREEN, Color.RED);
ColorDrawable cd = new ColorDrawable(color);
view.setBackground(cd);
