Correct Colours In .xls export

Hi,


I am trying to produce an excel xls form that has correct screen colour reproduction in numbers & when used as a .xls file in the numbers spreadsheet application


I have been trying this various ways but cannot seem to find a correct solution.


For example, I have tried filling cells with a RGB reference,


I can set correct RGB colour references for a fill colour say R 254, G,242 B,205 in numbers. This looks fine but if I then open in excel, these colours change to R 255, G 241, B193


I am not sure why.


I had thought of creating each colour as an image fill from numbers but excel does not support this option?


Could anyone advise me the best way to go about this please?

Imac 3.06 Intel, 4Gb RAM, Macbook 2.04 Intel 4Gb RAM, Mac OS X (10.6.5)

PflaumeGrau,


The difference can probably be explained by how you are checking the color. Do not use the Color Picker (magnifying glass icon). Doing this will result in your picking up the screen color, with perhaps some correction applied, and not the assigned color. To check the cell's assigned Fill color, Select the cell and click on the color patch in the Cell Background section of the Table Inspector, then read the RGB slider positions in the Colors Pane. I'm no expert in colors, but I know enough to warn you about this apparent shift when picking them from the screen.

Hi,


I have been looking this up in the correct way, the values do change between applications. I just tried this method.


Opened the form in excel, set the fill colour of one cell to R 255, G 241, B193 saved & closed. Quit excel..


I opened the just saved file in numbers, the same cell now has the rgb color reference of R238 G220 B163


I am checnking all of this from the fill colour in the inspector, not using the colour picker.


Doen any one have any idea what is going on here or a way to work around this?


Really, I just want to make a .xls documnet that has good colour reproduction for anyone viewing it on screen.


Currently, the colour changes happening are really drastic between the two applications & I just dont understand why?

For many years, I have never been able to convert an MS Office document (any app in the suite) and have the colors translate exactly the same in the corresponding Apple program, nor vice versa. It is especially annoying with presentations.


The only explanation I've ever gotten is that MS Office programs do not use fully standard color palettes, but I've never delved into it much. Its nothing new to me though, and if you are trying to save cross platform and keep colors just so, you will end up with little to no hair left, and files that still look different in the end.

Hi,


Thanks for the insight!


I just find that really strange when selecting rgb values, I would expect them to stay the same?


If i was going from a pallet then I would understand...


Do you think there is any other work around? Maybe to use images of colours some how?


I know the image fill is not supported in excel but could something else be?


I have posted the same question to the microsoft excle forum yesterday but not one reply as yet...

At least with older versions of Excel, I believe they actually did not use RGB per se, but rounded the values to the closest thing in their 56 color palette. So even though it said RGB, it actually was not. I thought that had changed at least, since Office 2007 or older.


Honestly I have never found a solution. With presentations, I know if I make one in Keynote, but the forum specifies they will be use Powepoint, I make it a point to check my slides in Powerpoint on a Windows machine. Even in the past, going from MS Office for Mac to MS Office for Windows did not maintain colors (although they would usually be close and not so much it rendered things unreadable). I never did get a real answer to why their own product on different platforms was not consistent in color - even HEX colors would be off


Hopefully some people on the MS side will have a better answer for you - I just got frustrated pursuing it years ago and just gave up looking for an explanation or fix. I suppose it is possible that excel still has some internal library fixed limit on colors (hopefully more then 56 by now) and is in fact, matching your values "as close to" its internal limts as possible. I also seem to recall that at one time, the RGB function in excel actually returned values in the order BGR - don't know if that still applies either.
