A method of converting a three-primary input color signal (IS) comprising three input components (R, G, B) per input sample into an N-primary color drive signal (DS) comprising N = 4 drive components (D1, ..., DN) per output sample for driving N sub-pixels (SP1, ..., SPN) of a color additive display. The N sub-pixels (SP1, ..., SPN) have N primary colors. The method comprises adding (10), to three equations defining a relation between the N drive components (D1, ..., DN) and the three input components (R, G, B), at least one linear equation defining a value for a combination of a first subsetof the N drive components (D1, ..., DN) and a second subset of the N- drive components (D1, ..., DN) to obtain an extended set of equations. The first subset comprises a first linear combination (LC1) of 1 = M1 < N of the N drive components (D1, ..., DN), and the second subset comprises a second linear combination (LC2) of 1 = M2 < N of the N drive components (D1, ..., DN). The first and the second linear combination are
