Delete NDVI Values from Satellite Image

[İrfanMoğulkoç]

Hello,

I want to delete NDVI/NDWI values from Satellite Image. For that, firstly I generated indexes and exported by using Raster Calculator with setNull. I used this formula;

SetNull( ~IsNull("NDVI_intense_regions.tif"),"Satellite_Image.tif")

When I apply this formula, result is good but output file is not RGB ;

How can I delete NDVI values? Or how can I convert this product to RGB?

Regards,
