Two-dimensional data colourings are an effective medium by which to represent three-dimensional data in two dimensions. Such color-grid representations have found increasing use in the biological sciences (e.g. microarray heat maps and bioactivity data) as they are particularly suited to complex data sets and offer an alternative to the graphical representations included in traditional statistical software packages. The effectiveness of color-grids lies in their graphical design, which introduces a standard for customizable data representation. Currently, software applications capable of generating limited color-grid representations can be found only in advanced statistical packages or custom programs (e.g. micro-array analysis tools), often associated with steep learning curves and requiring expert knowledge.
