A transparent to white `Brush.verticalGradient` in a white `Box` renders gray with `drawWithCache` . A bug? Code in :thread:

```Box(
  Modifier
    .size(50.dp, 50.dp)
    .background(Color.White)
    .drawWithCache {
      onDrawWithContent {
        drawContent()
        drawRect(
          Brush.verticalGradient(
            .5f to Color.Transparent,
            1F to Color.White
          )
        )
      }
    }
)```

I'm not at a computer atm but i think transparent might set the other color channels to zero, and so it ends up interpolating between transparent black and opaque white which gives you the gray?

You could try doing `Color.White.copy(alpha=0f)` instead of `Transparent`

That's fantastic, Zach. Thank you. Should I report that as a bug? The gray gradient seems rather strange seeing as `Color.Transparent` was set.

I don't think it's worth filing a bug, I think you just have to be careful when lerping colors that if you only want to lerp the alpha channel, you make sure that's the only channel that's different.
