Cytosketch provides a tool to add and format text. To add text, click the Text tool , click on the canvas and start typing.
You can change the color and the font of the text. Cytosketch also provides buttons to easily add Greek letters.
Cytosketch has a special feature to ensure that you always have a good text color for your figure. When the color of the text is set to default, Cytosketch automatically adjusts the color depending on what is underneath the text. If the text is on a dark image then the text will be white, on a light image the text will be black. See below for an example.
