This paper proposes two simple and powerful algorithms to automatically paint Celtic
knots with aesthetic colors. The shape of the knot is generated from its
dual graph as presented in [KC03]. The first technique uses rules derived from two-colors harmony
studies in a Color Order System to select harmonious color pairs. We show that
it can efficiently reproduce color combinations utilized in ancient and modern Celtic design. The
second technique aims at creating knots with a rainbow type colorization that
can be seen in modern Celtic art. The user controls a few parameters
like the number of desired different hues, or the average brightness and
saturation expected, by defining an ellipse in the color space. The program then accordingly
selects a series of colors. In both cases, we apply rules issued from prior
Color Science studies.
