Embodiments herein include a method, service, apparatus, etc., that receives initial user input comprising natural language commands that identify the initial color selection. The method displays the initial color samples or patches corresponding to the initial color selection in a two-dimensional grid and receives additional user input comprising additional natural language commands and a refined axis selection. The embodiments herein revise the initial color selection to a revised color selection based on a color change magnitude, a color change direction, and a color change property. Then, this method matches the revised color selection to the computer program colors to produce refined matching colors. These refined matching colors are displayed as refined color samples or patches in the two-dimensional grid. The axes of the two-dimensional grid can correspond to the refined axis selection and the assigned names can also be displayed on the graphic user interface.
