React-native: [Android] borderColor is broken for transparent colors
Setting borderColor: "rgba(255, 255, 255, 0.5)" works but borderColor: "rgba(255, 255, 255, 0.6)" gives a black border.

Sorry for the delay, still an issue on 0.16 but I haven't had the time to upgrade to 0.17 or 0.18.

I'm seeing this in 0.17, however opacity of 0.5 also appears as black.

I'm also seeing this in 0.17 on Android
I've tried a number of combinations...for e.g.
mystyle: {
height:1,
borderBottomWidth:1,
borderColor:'rgba(255,255,255,0.5)',
borderTopWidth:0,
borderLeftWidth:0,
borderRightWidth:0,
},

Seeing this on master, seems related to color parsing? cc @andreicoman11

Happening in 0.22 still. Black border for any alpha value except 1.0.

Happening still in 0.23.0-rc. It seems like instead of a real opacity being calculated, a different color value is being applied. So, the blacks turn into greys, but are fully opaque.

Hi all, I have a pull request to fix this here: https://github.com/facebook/react-native/pull/9380
Problem had to do with storing int value as float. This is lossy when converting back to int for very large numbers. To solve this I split color (ARGB) into RGB and Alpha values to be stored separately.

Many thanks to @foghina for reviewing and getting the pull request merged in today - if @cosmith and others here can confirm this bug is fixed that would be appreciated!

Closing this due to 8095707
Let's reopen if it's not fixed.
