A roof color name does not tell you the measured reflectance of a particular finish. Energy-related comparisons require product data and building context. Two finishes with similar appearances may have different documented properties.
What to do next
Request the exact finish information and any relevant tested ratings. Compare appearance, maintenance, exposure, and potential energy effects separately. Avoid accepting a promised utility saving that does not account for the building's insulation, cooling use, and existing conditions.
