Need help scrolling through colors

Configuration
1

I am trying to figure out how to get a button to scroll through colors.

I am currently using Lutron Casata Pico remotes to control my color lights. I have ON, Off, and Brightness working with a blueprint (stephack/core-pico.yaml). I would like to use the middle button to scroll through colors. I have been trying to figure out how to do an if than statement with no success. I need something like this:

if
light is white then change to blue
if
light is blue change to red
if
light is red change to green
if
light is green change to white

I don’t see away to select a color from the automatons or scripts so I’m stuck.
Someone please point me in the right direction.

Thanks. This looks like what I need but I can’t get it to work in the automation. I get error

“Error loading /config/configuration.yaml: while scanning for the next token
found character ‘%’ that cannot start any token
in “/config/automations.yaml”, line 249, column 14”

am I missing something? Thanks again for your help.

You are using a device id instead of an entity id in the is_state_attr() tests. This not supported as far as I am aware. You should avoid using device ids as much as possible. They are not easily changed if you replace a device. Entity ids can be changed (new to old) in one place.

This automation was created with a blueprint. I changed it to device_id and I still get the same error.

Error loading /config/configuration.yaml: while scanning for the next token
found character ‘%’ that cannot start any token
in “/config/automations.yaml”, line 249, column 14

line 249 is {% if is_state_attr(‘light.desk_light’, ‘color_name’, ‘white’) %}

I tried to look at the template info from the link you posted but can’t see a problem. Is it possible to use template info in a yaml file?

Opps. This:

        data:
          color_name:
            {% if is_state_at...

Should be:

        data:
          color_name: >
            {% if is_state_at...

I missed the multi-line template symbol. Sorry.

I have not been able to get this to work so I thought I would try to create a script that would change the light from white to blue and blue to white. I can not get that to work ether. I tried to use the gui in HA but there was not a color_name option under state so I added it in yaml. Here is what I tried. Please, please, let me know what I am doing wrong.
