Color Picker in Blender 2.57

Coding Python Support
1

Hi,

I couldn’t find any python code for a color picker under Blender 2.57.
I have found something like Blender.Draw.ColorPicker(), but it is old.

Is there a new way to use a color picker ?

Thanks a lot

Remember, the 2.5 interface is written in python, so you can simply browse the python files for clue.

Here is the default simple panel with a color picker property added.


import bpy


class OBJECT_PT_hello(bpy.types.Panel):
    bl_label = "Hello World Panel"
    bl_space_type = "PROPERTIES"
    bl_region_type = "WINDOW"
    bl_context = "object"

    def draw(self, context):
        layout = self.layout

        obj = context.object

        row = layout.row()
        row.label(text="Hello world!", icon='WORLD_DATA')

        row = layout.row()
        row.label(text="Active object is: " + obj.name)
        row = layout.row()
        row.prop(obj, "name")
        # Material Property Added
        mat = bpy.data.materials["Material"]
        row.prop(mat, "diffuse_color", text="")


def register():
    bpy.utils.register_class(OBJECT_PT_hello)


def unregister():
    bpy.utils.unregister_class(OBJECT_PT_hello)


if __name__ == "__main__":
    register()

The color picker is activated based upon the TYPE of the property. So to use a custom property value, you will need to create it as a color type.

How to create a custom color property value?

I tried to convert bpy.props.FloatProperty to bpy.props.ColorProperty but of course it doesn’t work :wink:

EDIT: use FloatVectorProperty with subtype=‘COLOR’

bpy.types.Scene.customColor = bpy.props.FloatVectorProperty(
    name="Value",
    description="Color value",
    default = (0.0, 0.0, 0.0),
    subtype='COLOR'
)

you need to add min and max of 0.0 and 1.0 to make it work properly

Yes! Thanks, it works better like that.

I want add color palette in Blender.
How to create a color picker, without linking (just like colored button) for some material?
Thanks for any help!

the color wheel is a C-coded widget, you can’t extend it with python.

Psy-Fi works on a color palette system, you should contact him via IRC.

I found this add-on http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Paint/Palettes Its code is very complex :frowning:
And I want create something like it, but simpler. Only 5 color-picker’s elements in “helloworld” panel, without any features.
Can you help me? Please!
