only 'sepia' look in results

[brcisna]

Hello All,

Trying out the colorize model.
Each image i try and do the --interactive colorize the results are all what looks like a 'sepia' / antique looking effect to the rendered photo. There is no actual color.
Have tried exporting each image into various formats such as jpg,bmp,png ,as well as converting from grayscale to RGB mode,with no different results.
Is there something am missing maybe?

Thank You

Hello foamilu

Here are two B&W photos , before and agter colorized. One original is very sharp resolution. One is not very sharp.
After rebooting computer one of the images does show some color after rendered but colors are way off. Could it be it is auto images and not humans with natural background?? Also, could it be the weak graphics card? Have read in the past on many of these imaging rendering softwares,if you do not have a good NVidia card you will never achieve good results? 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)

Thank You
