Uniformly white or grey screens are employed almost exclusively as to avoid any discoloration to your image, while the most desired brightness from the screen depends on various variables, such as the ambient light level plus the luminous power of the particular image source. Flat or curved screens should be used depending on the optics accustomed to project the image along with the desired geometrical accuracy with the image production, flat screens being the harder common of the a pair of.
