+Subject: [PATCH] dt-bindings: leds: Expand LED_COLOR_ID definitions
+
+In commit 853a78a7d6c7 (dt-bindings: leds: Add LED_COLOR_ID definitions,
+Sun Jun 9 20:19:04 2019 +0200) the most basic color definitions where
+added. However, there's a little more very common LED colors.
+
+While the documentation states 'add what is missing', engineers tend to
+be lazy and will just use what currently exists. So this patch will take
+(a) list from online retailers [0], [1], [2] and use the common LED colors from
+there, this being reasonable as this is what is currently available to purchase.
+
+Note, that LIME seems to be the modern take to 'Yellow-green' or
+'Yellowish-green' from some older datasheets.

+Subject: [PATCH] leds: core: Add more colors from DT bindings to led_colors
+
+The colors are already part of DT bindings. Make sure the kernel is
+able to convert them to strings.
