Change canvas color with listpicker

[dora paz]

Hello,

I followed the paintpot tutorial part 1 and part 2 and i tried to change the size of the line and change canvas color with listpicker. I managed to change the size of the line and to change the canvas color using listpicker but in my list doesn't show the color name but the number of the color.

Any help appreciated , Thank you in advance

This list of colors to numbers might help you do what you want to do  http://appinventor.mit.edu/explore/app-inventor-color-chart.html Dora. You can use the information to construct your own color number to color name listofpairs and display the color name in the ListPicker instead of the number.

Regards,

Be sure to check out the lookup-in-pairs block from the Lists section of the

Blocks Editor to transform the English color names into their 

color values after Selection.

The color table SteveJG mentioned looked so handy, I thought I would

post the skeleton code to bring it in as a table for lookup.

See attached.
