Abstract: A dental color system is provided, which comprises a smaller number of primary colors and mixed colors and has the optimum colors conformable with natural teeth adjacent to a dental prosthesis. A dental color system includes primary colors and mixed colors assigned to coordinates in the CIElab color space in which the colors of natural teeth are primarily situated on coordinates within an oval space(18) having an assigned longitudinal axis(22). The primary colors consist of first primary colors(32,34,36,38) and at least one group of second primary colors(112). The coordinates of the first primary colors are situated on a baseline that extends from light to dark in the CIElab space and on the longitudinal axis of the oval space. The coordinates of the at least one group of second primary colors are situated on a plane(107,109) that intersects the longitudinal axis or baseline at right angles. The coordinates of the mixed colors are intersecting points of first and second straight lines(114), whereby at least one straight line extends parallel to the longitudinal axis or baseline and each of the second straight lines connects one coordinate of the first primary colors with one coordinate of the second primary colors.

Abstract translation: 提供了一种牙科颜色系统，其包括较少数量的原色和混合颜色，并且具有与邻近牙科假体的天然牙齿相适应的最佳颜色。 牙科颜色系统包括分配给CIElab颜色空间中的坐标的原色和混合颜色，其中天然色的颜色主要位于具有分配的纵轴（22）的椭圆形空间（18）内的坐标上。 原色由第一基色（32,34,36,38）和至少一组第二原色（112）组成。 第一基色的坐标位于CIElab空间和椭圆形空间的纵轴上从亮到暗的基线。 所述至少一组第二原色的坐标位于与纵轴或基线成直角相交的平面（107,109）上。 混合颜色的坐标是第一和第二直线（114）的相交点，由此至少一条直线平行于纵向轴线或基线延伸，并且每个第二直线将第一基色的一个坐标与一个 第二基色的坐标。
