    Hello,

    Im trying to achieve a vibrating effect in the white colors in a project.
    I have been looking into different tutorials: flickering candles and street lights ec.t without any good results.

    I would like to have almost a vibrating white color spectrum.
    what would be a good and easy way to do accomplish this?

    tips and inputs are much appreciated,

    Thanks!

    Without knowing what “good results” are to you or what a “vibrating effect” means to you, we can’t be any help getting you there. White is not a color spectrum.

    Taking a random guess at what you want, if I had an image with white in it and I wanted it to randomly cycle through colors I would use the “change color” effect. I’d set it to match white and filter it so it grabbed only my white object. Then I would reduce transform lightness to -50, transform saturation to 100 and put an expression on the transform hue with something like wiggle(1.2,180).

    If I understand correctly, you are trying to achieve a super bright light- if that is so, you need to work in 32 bit – adding a glow will help to give that illusion.

    Hi Cory,

    I should have been more specific about my project.
    But your guess is very correct. I never thought of the expression, I’ll give it a try.

    here is some reference material: https://vimeo.com/7107401 (the lights in the background).

    Thanks for you answer.
