Color Picker High Sierra OS 10.13

In OS X El Capitan 10.11.6, the Colorpicker has a tiny, centered dot below the swatch rectangles. This “grip” would allow click and drag expansion to the full 10 rows and 23 columns that are/were available. This “grip” is gone with the High Sierra (and possibly Sierra) ColorPicker and is restricted to 26 swatches, with no expansion remedy.

An alternative is to create Color Sets (the third ColorPicker toolbar icon) via the gear selector, and click on the individual members of this set to apply custom colors. These .clr color sets are saved in ~/Library/Colors. In the following, I added teh RGB and Hex information as additional documentation for the individual colors. I also have some optional color pickers installed.

You can also send feedback to the macOS team.

I believe that's all there is.

Don't remember any more than 2 rows.

Tell Apple what missing features you'd like restored or new features added in Photos via https://www.apple.com/feedback/photos.html.

I don't remember having more than 2 rows available. However, I checked some of my 3rd party apps and found some of them have more than 2, i.e. Acorn, SketchIt, etc. but then went to resize the color wheel window and they reverted to two rows.

It is what it is I guess.

I see 3 colors in your screen shot. What is your problem and where??
