Astia does tend toward the cool side, but it responds nicely to warming filters without going overboard. I have one batch that I always rate at 80 and use an 81A or KR1.5 filter with for a neutral result. I have another that I rate at 100 and don't use a filter with unless it's needed. With natural light indoors it looks good with a KR6, which is about an 81C.
