The present invention, additional to Patent 89-10249 of 28 July 1989 by the same authors, relates to an extension of the additives of the said patent, details concerning the nature of the additives and the method of mixing thereof, in order that the latter, added to solid, liquid, pasty or gaseous/liquefied fuels, may constitute a mixture or a solution which, on burning, will produce flames of chosen and varied colours. Emphasis will be placed in particular on the colours blue and white, reputed to be difficult to obtain in a clearly visible manner and not mixed with other associated colours. Fuel(s) and container(s) will be heated for a spontaneous appearance of the flame colouring, imperatively, chiefly in the case of the reds and the blues.
