Using filters to view Mars:
Yellow (W8) Enhances Martian cloud details.
Yellow (W12, W15) to brighten desert regions, darkens bluish and brownish features.
Orange (W21, W23A) further increases contrast between light and dark features, penetrates hazes and most clouds, and limited detection of dust clouds.
Red (W25, W29) gives maximum contrast of surface features, enhances fine surface details, dust clouds boundaries, and polar cap boundaries.
Yellow-green (W57,W11) darkens red and blue features, enhances frost patches, surface fogs, and polar projections.
Blue-Green (W64) helps detect ice-fogs and polar hazes.
Blue (W80A, W38, W38A) and deep blue (W46, W47) shows atmospheric clouds, discrete white clouds, and limb hazes, equatorial cloud bands, polar cloud hoods, and darkens reddish features.
