Claim One:
1. A method of displaying two dimensional color images, comprising the steps of: generating a first light beam having a first wavelength to excite first particles located in a transparent display medium; generating a second light beam having a second wavelength to excite second particles in the transparent display medium, the first wavelength being different than the second wavelength, the first particles being different from the second particles; absorbing the first light beam in the first particles located in the transparent display medium; absorbing the second light beam in the second particles in the transparent display medium; forming a first visible light color from the first particles being excited by the first light beam; forming a second visible light color from the second particles being excited by the second light beam, the first visible color being different from the second visible color; and moving the first light beam and the second light beam to excite different particles in different places in the display medium to form the two dimensional image in two colors.
