You can put ECOS over any water-based paint so long as the surface is free of dirt, dust and oil. If you have the existing paint's color name and the brand, ECOS can match it, but it will probably not be 100% the same color due to your wall's exposure to UV light. Since your doing touch ups there's a high risk it will be noticeable next to the existing color. ECOS is very good at matching other brands' colors, but it is still a different paint and might not match perfectly.
