Hey @juan manuel de M�xico
There are several ways to download in Labs & Trends :
Jpeg as you mentioned.
ASE & Others
One's we created only Jpeg

In terms of activating the colour swatch:
1) Top right corner on the "homepage" under the swatch you can see
Save to: "library name" and a "+" symbol
Press the "+" symbol to create a personalized library.
2) Name the swatch as you see/ deem fit.
3) Viewing or seeing the pretty simple in Photoshop, Illustrator, Adobe Express you will see "Libraries"
In Libraries, a folder named "Lighting" (as is the case in the screenshot will show).
Open the folder and you can see the swatches you saved and named.

Deleting Swatches
Go into your Adobe: Creative Cloud
Open Files
Files: find the folder with the swatches you want to delete.
