Issue Description

node, npm, react-native, react and native-base version, expo version if used, xcode version

react-native - v0.60.5 native-base - v2.13.5

Expected behaviour

It should show blank no tick box

Actual behaviour

It shows black tick

Steps to reproduce

   style={{ borderColor: type.checked ? 'blue' : 'black' }}
  checked={false}
  color={'blue'}
  onPress={() => true}
/>               

Is the bug present in both iOS and Android or in any one of them?

Yes

Any other additional info which would help us debug the issue quicker.

FYI: The issue seems to have been introduced in “CheckBox Cleanup (#2777)” It used to default the checkBoxBgColor to “transparent” but now sets it to “checkboxDefaultColor” which from what I can tell doesn’t exists in the theme variables. Workaround is to add this to your “variable.js” file: "checkboxDefaultColor": "transparent"
