Created an automation to look at solar production and house consumption and use this to create a smooth gradient going from green to purple:
[0, 255, 0], # Green
[255, 255, 0], # Yellow
[255, 165, 0], # Orange
[255, 0, 0], # Red
[128, 0, 128] # Purple
I’ll post the yaml from the automation below, feel free to adapt or turn into a blueprint:

Make adaptions to the jinja template to use your own sensors and lower and upper limits. Play around with the template in your dev tools to get it right for your own setup:
{% set colors = [ [0, 255, 0], [255, 255, 0], [255, 165, 0], [255, 0, 0], [128, 0, 128] ] %}
{% set min_val = -3000 %} **#changethis to max solar**
{% set max_val = 2500 %} **#changethis to value from where you want to see purple**
{% set house = states("sensor.house_consumption") | float %} **#change this to your actual sensor**
{% set solar = states("sensor.solar_power") | float %} {% set value = house - solar %} **#change this to your actual sensor**
{% set normalized = (value - min_val) / (max_val - min_val) %}
{% set num_colors = colors | length %}
{% set segment = (num_colors - 1) * normalized %} {% set index = segment | int %}
{% set weight = segment - index %}
{% if index < num_colors - 1 %}
{% set r = (colors[index][0] * (1 - weight) + colors[index + 1][0] * weight) | int %}
{% set g = (colors[index][1] * (1 - weight) + colors[index + 1][1] * weight) | int %}
{% set b = (colors[index][2] * (1 - weight) + colors[index + 1][2] * weight) | int %}
{% else %}
{% set r, g, b = colors[-1] %}
{% endif %}
[{{ r }}, {{ g }}, {{ b }}]
