Warm filter

A warm filter is a photographic filter that improves the color of all skin tones and absorbs blue cast often caused by electronic flash or outdoor shade.[1] They add warmth to pale, washed-out flesh tones and are ideal for portraits as they smooth facial details while adding warmth to skin tones (for color imaging).[2]

In general, they suppress blue casts on overcast days and on subjects lit by blue sky.[3]
