Question 2

What's the difference between the Holo and Triangle color pickers?

Question 3

How to handle color changes in a controlled component with this library?

Accepted Answer

This library stands out with dual picker styles and controlled/uncontrolled support, but it lacks advanced features like alpha channels. Alternatives might offer more customization or better ScrollView compatibility, so choose based on project needs.

Question 5

Accepted Answer

Use props like 'hideSliders' for Holo picker or 'hideControls' for Triangle picker to toggle UI elements. Additionally, apply custom styles via the 'style' prop to adjust size and layout, but note that core visuals are fixed.

Question 6

Does react-native-color-picker support alpha channel (transparency)?

Accepted Answer

Question 7

How to fix touch issues when using the color picker in a ScrollView?

Accepted Answer
