Abstract
The preliminary results of the study of visual and infrared colors of different types of stars with infrared excesses are presented. We have found that in most cases more warm dust exists around the objects with cool central stars than with hot central stars. Two possible symbiotic stars AS 201 and HD 330036 show infrared colors very differ from other symbiotic stars. We suppose that these objects may be young planetary nebulae.
