- Bright, Vibrant, Primary Colors
- High contrast in wardrobe elements
- Loud stripes
- Tight, repeating patterns (Iike herringbone)
OK 
- Muted earth tones, pastels, greys
- Broad patterns are OK
- Pinstripes are OK, if not highly contrasting
- High-saturation colors, especially red, can "bleed" on VHS videotape, and other non-broadast formats.
- High contrast in wardrobe elements are more difficult to light for TV
- Stripes, checks and certain patterns can create an optical "moire"- an electronic phenomenon that looks like cycling rainbows. You've probably seen this in shots of NFL referees.
Tight patterns and stripes can create a pulsating "moire". Avoid them.
