What is the purpose of using a colored bottle? Well made CS will absorb light only in the UV region, and regular glass will absorb in the uv region. If your EIS is yellow or gold then that means that it is absorbing in the violet and blue region. To degrade it HAS to absorb light, so that means that to prevent degradation you should block light of the color it absorbs in. Since a cobalt blue blocks all but the blue and violet light, it would not help at all, you need something that blocks blue and violet, which will give the compliment color which is yellow or brown.
