Composition and method of making a combustible organic mixture used to generate a colorful flame that is environmentally safe and non toxic. In accordance with the invention there is provided a fuel blend mixture of hydrocarbons, alcohols, glycols or glycol ethers with a color flame generator in the form of an organometallic complex such as acetyl acetonate complexes of alkaline, alkaline earth or transition metals such as lithium, cesium, sodium, and copper acetyl acetonate complexes. The homogenous material can be used as a fuel in various types of candles and lantern devices to generate flames of red, yellow, blue, green or purple color and variations thereof depending on the organometallic complex that is used.
