Yes, you can. It will have a negligible effect on colour balance under artificial light, but it will still provide physical protection for your lens.
These are codes for the strength of the colour correction. 1A is a very faint pink tint. 1B (or 'Skylight') is slightly stronger, offering more warming effect. Both are subtle.
