Field isMonochrome has the same name as a method

This issue is known as a naming conflict, where a field and a method in the same class have the same name. It can cause confusion when referencing the field or method, and can lead to errors in the code.

To resolve this issue, one option is to rename either the field or the method to have a unique name. Another option is to use naming conventions to distinguish between the field and method names, such as using a prefix or suffix for one of them. For example, you could rename the field to "isMonochromeFlag" or rename the method to "checkMonochrome"
