RE: coloured beads.
What equipment and what procedure did you use? I presume you had two different colours, and you mixed them in some way. Can you clarify what you did?

Could you recommend me some experiments that show equilibrium

Hi. There are certain classic lab demonstrations of dynamic equilibrium in a closed system.
The important feature we need to show in our model is that, at equilibrium, the rates of the forward and reverse reactions are equal.
I want you to think about the true aspects of each model, and the limitations of each model.
Most of the models use separate containers for products and reactants, but that is not how a closed chemical system works, is it?
In a closed chemical system (most of the time) products and reactants are in the same vessel.
(1) Transfer of a liquid between two shallow trays, using different size beakers. Here is a link.
(2) Transfer of coloured beads between two deep containers. Here is a link.
You can find videos for most of these classic demonstrations.

So a limitation would be how it’s open
And how it’s not part of one system
