Colour combination under water

[Abhann]

Okay, so blue water plus reddish-orange tiles equals green tiles.  What colour would I make them to have them show up orange again?  or just red even?  In PaintShop I could do it but with TFP my brain is blanking

Hi Abhann,

Principle is the same as Paintshop really. Are the other tiles blue or just the water?  The only way you would get the green ones to show orange is to make the water transparent or just an extremely pale blue.

Thanks Allan,

The other tiles are blue (lucky choice!).  In PaintShop I would use filter masks and things.  TFP is actually more realistic the way colours show.  I'll try making the water more transparent.

Great ideas on swimming pools, by the way, I was just reveiwing some of your other posts. Very helpful.

You can experiment with colors/transparency/overlays in TFP (better because that is what you are using) or Photoshop or Paint Shop or any similar program.

Blue over orange gets dark green because blue+yellow=green and orange has plenty of yellow (plus red)...the red makes it all darker toward brown.

Also color issues happen because of reflections....such a blue sky onto a gold/copper color = greenish yuk.

You can try to fix with colors in TFP before render, or go to Paint Shop and 'recolor" areas as needed with masks....which is easier depends on the user skill in each program and render times.

Experimenting is about all you can do; but intelligent guesses using a color wheel can point you in right direction. But mixing paint/print (CMYK) ink vs. RGB on a illuminated light based screen is different.

And be sure to experiment all the way to a print on paper (including the final paper choice) (if print is the final product) because subtle color changes happen along the process from start to end.

Hi Abhann,

It may be worth mentioning here a couple of other things about use of colours in TFP that you may not know that may help in this or other situations:

1. There is a difference between using Colours and Textures. Textures work better than using a colour and  olours can sometimes be lost. See this post (from Reply 39-44) on the disappearing fence : http://forums.turbofloorplan.com/index.php/topic,1954.30.html. So it is better to ceate a BMP image of colour in PaintShop than to use just a colour from the Windows colour selector.

2. If you want a reflection on the water in a pool  you need to have objects or images near the water for it to reflect. You will not get a reflecfion of the sky for example from your Background image because the background image is not technically a part of the 3D model it just sits behind it. To get a sky reflection you would have to us a very large image as a photoboard and place it at the back of your model. An image placed like this will reflect.

You may have been aware of these points from reading previous posts but thought I would mention them just in case.

To get a sense of mixing paint colors (as a painting artist would do), see this site to play with mixing colors:

Thank-you everyone,

I had great fun experimenting with your suggestions, and learned some tricks for other projects, but the bottom line is that orange is a bad colour for pool tiles

I had "green fence" problems a while back so I knew about the difference between colours and textures.  I had not been thinking of the effect of reflections, especially reality vs TFP style backgrounds, so thanks for useful info on that.

I actually enjoy doing 2d floorplan and layout, and in past only redndered the minimum to visualize the space.  Now that my system is up to more realistic rendering it's been fun learning some of the ins and outs of it - next: Animations

Animations are a whole new ball game but fun. They will test out your computer resources too. Keep the animation size small to start with until you get the route correct unless - you are very patient!
