IGColorPicker

Only supports check or no selection indicators, with the ToDo list admitting the need for custom check size and custom view support, restricting visual flexibility.

Relies on M13Checkbox for selection indicators, which is noted as a potential issue to be replaced, adding maintenance overhead and potential compatibility problems.

Focuses solely on grid-based color selection and lacks advanced features like color wheels or gradient pickers, making it less suitable for complex color manipulation apps.

Customizing layout requires implementing delegate methods for size, spacing, and insets, which can be more involved than simple property adjustments, increasing development time.
