Short description of error

Texture gradient is not displayed correctly. Texture Blend.
When you configure the texture, the preview displays the texture view.
The preview is more white than black.

If the texture to use as brush, you can see that the boundary particle moves wrong.

If in 2.8 open the file created in 2.7.
The texture is displayed differently.
But it works the same way as in 2.7.

Exact steps for others to reproduce the error
Run the attached files, see how the particles behave.

Blender 2.8 uses Filmic color management by default, which has this effect. It looks odd but it's a result of how scene linear colors are not linear display space colors.

No bug here as far as I can tell.

English is not my language, apparently the translator spoils the sense.
I tried to.

The gradient preview is not true.
In other places (and in other programs) the gradient shows how the color changes.

In the screenshot of the gradient node, the gradient texture settings shows really how the color changes.

The fact that the Blender 2.7 floor texture is not generated smoothly gradient, I'm not talking about it.

Previews of textures show the truth.

The 2.8 gradient preview shows no truth.

The texture generated in 2.7 is not smooth.
But this texture works the same way light is positioned.
First, almost half of the particles fly away.
Then the gradient part.
And, almost half of the remaining particles.

2.8 generates a smooth texture.
Particles take off smoothly
The preview shows the lie.
