An optical see-through display apparatus includes an image output module, a display panel, an optical shutter panel to adjust a transmittance of an external light for each of R, G, and B colors. The display apparatus includes an optical sensor to measure a color of the external light. The display apparatus includes a processor that generates R, G, and B shutter data through a first compensation algorithm. The first compensation algorithm is operated to: compare a color of a mixed virtual image with a color of a target mixed virtual image, and when a color difference therebetween is a threshold value or less, designate a transmittance of the optical shutter panel as a candidate transmittance, and select a candidate transmittance implementing the mixed virtual image most similar to the target mixed virtual image, and generate the R, G, and B shutter data corresponding to the selected candidate transmittance.
