The NDVI Colorized function applies the NDVI function on the input image, and uses a color map or color ramp to display the result.
Below is an example of a Landsat scene using the 7,4,3 band combination on the left. On the right is the corresponding NDVI using a color map that highlights the agricultural activity. 
Notes
You can render or display your NDVI output with a color map or color ramp of your choice.
The default color map is named NDVI3. Red and orange pixels represent areas with no vegetation. Yellow pixels represent areas with low to moderate vegetation. Green pixels represent areas with high vegetation density and vigor.
