Change dimension text color

[gswifort]

I'm trying to change the color of dimension text. The best I've managed to do so far is change the color of every object in the dimension block. All other objects except the text change immediately. For the color change of the dimension text to show up I have to save and restart the drawing. Is there a better way to do this?
I assume I'm doing something wrong because the old color is still visible here:

dim: Db.Dimension = ...
btr = Db.BlockTableRecord(dim.dimBlockId())
for ent_id in btr.objectIds():
    ent = Db.Entity(ent_id)
    ent.upgradeOpen()
    ent.setColorIndex(...)

Generally, you would work through the dimension style or a dimension override
try the override

from pyrx import Rx, Ge, Gi, Db, Ap, Ed, Ax, command
# https://www.keanw.com/2009/09/creating-and-overriding-autocad-dimension-styles-using-net.html


# change the dimstyle
@command
def doit1():
    db = Db.curDb()
    dimStyle = Db.DimStyleTableRecord(db.dimstyle(), Db.OpenMode.kForWrite)
    old = dimStyle.dimclrt()
    
    clr = Db.Color()
    clr.setColorIndex(1)
    
    dimStyle.setDimclrt(clr)
    print(dimStyle.getName(), old, dimStyle.dimclrt())


# add dim override
@command
def doit2():
    ps, id, _ = Ed.Editor.entSel("\nSelect:", Db.Dimension.desc())
    if ps != Ed.PromptStatus.eOk:
        return
    dim = Db.Dimension(id, Db.OpenMode.kForWrite)

    # todo check if there's aready a dimstyle override
    # 178 = dimclrt
    # 1 is red
    xd = [(1001, "ACAD"), (1000, "DSTYLE"), (1002, "{"), (1070, 178), (1070, 1), (1002, "}")]
    dim.setXData(xd)
