Bright colors and unexpected materials rule this week’s gallery picks.

1. With extraordinary delicacy, Tom Phillips has dissected his previously used, discarded plastic palettes and converted fragments of them into intricate oil collages mounted on panels at Flowers Gallery
2. Jacques Roch’s paintings tell a narrative that comes close to the edge of a nightmarish darkness, taking a last minute playful turn with sexual daydreams and humorous, childlike doodles at Kim Foster Gallery
3. Jason Roth’s newest series of paintings on shop rags are explosions of multicolored forms that possesses a bold graphic flavor and tough, matte surface at Masters Pelvin
4. Shane McAdams and Caroline Jane Harris experiment with unusual mediums – paper, ball-point pen ink, resin – taking nature and landscapes as a starting point but with very different results at Scream London
5. For Ati Maier, the first Moon Walk serves as both metaphor and unifying theme to her latest exhibition, The Map Is Not the Territory at Pierogi 2000
6. David Poppie’s amazing work with colored pencils at Pavel Zoubok
