The color gradient heat map uses colors based on the values in the cell. For example, if you have values 70 and 90 and have set white for the minimum value and red for the maximum value, both values will be highlighted in red.

Since 70 is smaller than 90, a dark red color will be applied to 70, creating a gradient effect. Now, let’s see how to create a single color heat map in Google Sheets.

Steps to Single Color Heat Map in Google Sheets

Single color heat maps are dynamic. This means that when you change a cell’s value, the color will automatically change to reflect the formatting. Below, you will find instructions on how to create a single-color heat map.

The color gradient heat map is helpful when you don’t have fixed criteria. For example, to identify students scoring less than 40 marks, the cells below 40 will be given different shades of the chosen color, creating a gradient. However, if you have fixed criteria, such as wanting to know about students who scored less than 40, then all cells with those values will be colored in a single color.
