Color mismatch for skybox and background in FrameLayout in Android

[yicong123456]

Just have a little issue that I used scene.skybox to set the background color for surfaceview in android: scene.skybox = Skybox.Builder().color(1.0f, 1.0f, 1.0f, 1.0f).build(engine) . and I suppose it should be the same color as I set in xml:

however the colors were not match.

And I used FFFFFFFF for the rgba value and it should be the same value for Srgba and Linear type I think. Can someone help me out the reason of the color mismatch for the same value and thanks so much!.

That's because filament works in HDR by default and applies tonemapping. Either use an inverse tonemapping function to compute your sky color, or use a linear tone mapper on the Color grading API.
