Give the positional pattern custom colors. You can either set one color for all positional eyes, or specify a color for each one; and also choose different colors for inner and outer par of the eye
Simple example:
<QRCode
value="https://github.com/gcoro/react-qrcode-logo"
eyeColor='blue' // blue color for all corners of all positional eyes
/>Other examples:
// Color for each eye
eyeColor={[
'red', // top/left eye
'blue', // top/right eye
'#ffc0cb', // bottom/left eye
]}// Include color for the inner part of the top/left eye
eyeColor={[
{ // top/left eye
outer: 'yellow',
inner: 'black',
},
'blue', // top/right eye
'#ffc0cb', // bottom/left eye
]}
