MacOS: Can't make noise appear on a layer with color

[VectorCat]

The video tells the story. If I'm doing something wrong procedurally, I'm not seeing it. Thank you in advance.

Note: This is only correct up to a point but I can’t be bothered to re-write it as I’d only be repeating what’s in some later posts. See those later posts for better explanations.

Unless I’m misinterpreting what’s happening in the video, you can’t add noise to a Pixel Layer in the way you are trying to do it.

The Noise setting in the Colour Panel only affects Fill/Stroke colours and not pixel layers.

If you want to add noise to a pixel Layer then one option is to use the Add Noise Live Filter.

At the start of your recording the document contains no layers.
When the Fill tool was used APhoto automatically generated a Pixel layer so that the “paint” had somewhere to go.
Unlike a vector object this new Pixel layer’s Colour & Noise is “fixed” and, without resorting to FX, Filters, etc… can’t be changed after applying it. It can only be changed by applying a new fill colour.
Right at the end of your recording after you set the Noise level to 100% if you had used the Fill tool again on the layer, the first grey colour would have been replaced with the new one with noise.

This sentence is a bit misleading.

The noise settings affects any color, but for vector layers it can be changed any time after initial creation, whereas for pixel layers the color incl. noise must be chosen before using a tool like fill tool or brush.

A dirty trick allows to set noise later for pixel layers:

• add a group, and nest the pixel layer into it
• now when changing the color on group layer, the pixel layer gets the chosen color assigned in real-time.
• but beware: using a color on a group will enforce this color to all child layers, any pixel content will be overwritten.
• one of the following tool must be active: hand, move, fill, crop, color picker (others might work)
• shape, clone, or others do block the color panel (at least on iPad) when a group layer is selected in layer stack
• if you have a pixel selection active, fill is restricted to the selected area.

Yeah, careless wording made in haste I’m afraid.
I’ve added a note to my earlier post to point people in a better direction.
