To make Tortilla Strips: Heat oven to 375°F. Place 2 teaspoons of the oil in small dish; stir in 2 to 3 drops food color of your choice. Brush oil mixture over tortillas, working the brush until color is even. Repeat with remaining oil and additional colors. Using pizza cutter, cut tortillas into very thin strips. Bake about 8 minutes, stirring once, until crisp.
