How to get rid of background and change the color of detailed lines (floor plans)?

[Origami Unicorn]

Hi, does anyone know what would be the best solution to get rid of background of png file that has floor plans?

I have tried removing the background in photoshop, tracing the image in illustrator, but none of it seem to work well... I am not really good with Adobe Suite so I just don't know what is the good solution. 

Floor plans include detailed lines so tacing the image does not pick up those detailed lines. 

I have a floor plan that I want to get rid of the background of it so when I place the floor plan on the colored image, the white background won't show. 

My questions are:

How can I place detailed image (like floor plans) into indesign?

How can I change the color of floor plan without background?*

*I would like to change the color of floor plan lines in dark blue. but my original floor plan image comes with white backgrouund, with black lines. 

Hope it makes sense what I am trying to ask! Any suggestions, video links would be much appreciated!!!

Here is the example of what I want to do. Just to note, I am creating my portfolio in inDesign.

Hi as i think first invert the colors of this image so your drawing become black then image trace and do what you want in layers rest all depends on your image from autocad it should be high resolution too...regards

If the quality of the image you want to use is similar to what you showed here, Image Trace will not give good results.

Editing (inverting) and coloring would best be done in Photoshop.

Can you get a vector version of the drawing? this is almost always preferred over a .png (raster image). If you have a vector file, you may be able to open and edit it in Illustrator, changing the fill and stroke colors as needed, save it as an .ai or .pdf then place it into an InDesign file.

If you are editing a vector file in Illustrator, create a swatch of the desired color, select the existing line color and apply the swatch*. 

If you have no other option but a .png, you can open it in Photoshop, adjust the image so the lines are solid black only (Image> adjust> curves, and/or Image> Adjust> Channel mixer) save it as a grayscale .tiff (Image> mode> grayscale).

Place the .tiff into your InDesign file, using the Direct select tool (white arrow) select the .tiff and apply any swatch color to it, including white.

*tip: if you want the drawing to be white, create a new layer in Illustrator called "background" and add a fill color, just so you can see the white drawing above, save as a layered .pdf or .ai. Once placed into InDesign, use Object> Object layer options to turn off the unwanted background layer.

Thank you so much for replying me in details. 

I have my floor plans in Revit not AutoCAD. I am not sure how to export as vector file (I looked it up and it is svg file?)

Do you happen to know how to export as vector file from Revit? I looked it up but I had hard time finding one online.

The first choice would be to save-as or export-to a PDF, but I don't use Revit so I don't know what your options are, I did find instructions to print to a PDF, which should work for you:

If you can only print postscript (.ps), drop that into Acrobat, which will launch Distiller (part of Acrobat) and convert it to a PDF, if you see an option to embed the fonts, say yes.

Actually, can you export to a .DWG file? Illustrator should be able to open this and save it as .ai or .pdf.

For my part, you're welcome. Let us know if you have any more questions.

That was created in some form of vector art once, if quality is an issue for you, see if you can get that.

confused unicorn,

Further to what Luke and Met said, I believe the original was black artwork on a transparent background.
