I have a pixel shader that tries to return a static colour

```
float4 PPBright(PS_POSTPROCESS_INPUT ppIn) : SV_Target
{
    return (1.00f, 0.00f, 0.00f, 1.0f);
}

```

no matter the colour values it returns white, I can change the alpha values and it affects the colour (white, grey, black).

here's my cpp code:

```
g_pd3dDevice->OMSetRenderTargets(1, &BackBufferRenderTarget, DepthStencilView);
BloomTextureVar->SetResource(SceneShaderResource);
g_pd3dDevice->IASetInputLayout(nullptr);
g_pd3dDevice->IASetPrimitiveTopology(D3D10_PRIMITIVE_TOPOLOGY_TRIANGLESTRIP);
tech->GetPassByIndex(index)->Apply(0);
g_pd3dDevice->Draw(4, 0);

```
