Minecraft crosshair texture pack?

I changed my crosshair in Minecraft, but depending on the background, the color changes. How can you turn this off?

Maybe that's an optical illusion. Make the crosshairs wider. Maybe then it will work.

Maybe he accidentally made it half transparent lol.

Yes with Paint 3D it is quite possible

You mean that the crosshairs, which are normal white, on a z. B. Does the white block change color?

This actually makes sense to either increase the contrast or simply make the crosshairs visible.

To answer your question: as far as I know, you can't issue this function. At least not in the Vanilla Minecraft. But unfortunately I can't tell you anything about plugins / mods on this topic.
