Decision step_size
Title: Step size
Description: In the Sequence() formula, the integer to be added with each step between 0 and 255. A larger step size results in a smaller number of rows and columns. For computational purposes, choose a step size of 15 or greater, as the fill colour is going to be calculated (255/stepsize)^3 times.

Variable color_map
Title: Color Map
Description: An array with three indexes: R, G, and B. The cell fill in each element is determined by these indexes. The result is a color map. Step through the z-axis index to see how the colors change, too. You could, for example, use a slice of this map to define a range of colors for a graph, or in another CellFill() instance as a heatmap to show low to high values.~
~
The font color is dependent on the 'luminance' of the cell fill color.

Decision alpha1
Title: Transparency
Description: Level of transparency (alpha parameter) applied to the cell fill. A value of 1 means there is no transparency.

Decision Luminance_threshold
Title: Luminance threshold
Description: Luminance is a measure of how bright something is, and this parameter is the brightness below which the text will be displaed in black rather than white text. If you find the contrast between the text and the background color in the cells too low, adjust this number downwards.
