# How to add custom color picker in blender material panel?

I would like to add a custom colour picker for a custom material section. The colour picker should be below the red line in the image:

I found a code but this make the colour picker on the "tool panel" and not on the "material panel". This is the code:

import bpy

class POSE_PT_test(bpy.types.Panel):
bl_label = "Test"
bl_space_type = 'VIEW_3D'
bl_region_type = 'TOOLS'
bl_category = "Testing"

@classmethod
def poll(self, context):
return True

def draw(self, context):
self.layout.prop(context.scene, "test_color", text='Detail Color')

def register():
bpy.utils.register_class(POSE_PT_test)
bpy.types.Scene.test_color = bpy.props.FloatVectorProperty(
name="myColor",
subtype="COLOR",
size=4,
min=0.0,
max=1.0,
default=(1.0, 1.0, 1.0, 1.0)
)

register()


Hope someone can help me to change this code so that it will be on material panel and below the red line. Thanks in advance.

• To change your test code to be a panel in materials tab of properties space use bl_space_type = 'PROPERTIES' and bl_region_type = 'WINDOW' and bl_context = "material" . As for adding under red line in image above, (without an ugly hack) would need to edit into the draw code of that panel. Jan 31 '18 at 14:54

• @batFINGER Can you guide me to make it under the red line in the image above? I have tried the code suggested by you but it gives error on line bpy.utils.register_class(POSE_PT_test) Jan 31 '18 at 18:03

You need to change:

    bl_space_type = "PROPERTIES"
bl_region_type = "WINDOW"
bl_context = "material"


The panel will end up like this

class POSE_PT_test(Panel):
bl_label = "The title in the materials section"
bl_space_type = "PROPERTIES"
bl_region_type = "WINDOW"
bl_context = "material"
bl_options = {'DEFAULT_CLOSED'}
tag = 0

@classmethod
def poll(self, context):
return True
def draw(self, context):
layout = self.layout
col = layout.column(align=True)
col.prop(context.scene, "test_color", text='Detail Color')


This is a little late but hope it can help anyone else that comes here
