Selecting All Objects By Text Color [Powerpoint]

Hey, I'm trying to select all text boxes in a powerpoint file by the color of the text. Once selected, I would like to change the color of the text. Is it possible to enumerate all the text boxes in the file and then go through one by one? If so, what methods would I need to use? Thanks.

This code enumerate all objects on all slides in the first presentation.
It checks for text boxes with forn color 0 (black) and replaces the color with 255 (red). Just remember that a text box can have multiple text formats (colors, fonts, sizes etc), and this code will only check the first font format and if the color matches it will replace the font color of the entire text box.

VB Code:

Dim app As Application
Dim sl As Slide
Dim shp As Shape
 
Set app = Application
 
For Each sl In app.Presentations(1).Slides
    For Each shp In sl.Shapes
        If shp.Type = msoTextBox Then
            If shp.TextFrame.TextRange.Font.Color.RGB = 0 Then
                shp.TextFrame.TextRange.Font.Color.RGB = 255
            End If
        End If
    Next shp
Next sl
 
Set shp = Nothing
Set sl = Nothing
set app=nothing
