yellow/blue is another complementary rgb color pair, which also looks quite nice to me :) although i think i'm more a fan of dark dirt and light twall color, this particular combination has something imo. i find the contrast very striking!

me too! :-D in fact, my cave 1509 originally had blue t-wall and yellow dirt, but at some point during development i swapped both colors because i liked the darker dirt better. :-)

 Arno , i just cloned your 1509 and swapped the two colors. i also like your actual version better. i think it's because with darker dirt, there's a better contrast between dirt and \\\/|||/brick walls/fireflies (the elements which are often randomly placed within dirt areas) :)

My favorite colors so far are from  Arno 's Golden Oldie 7 and 15 :D there was also one where white is replaced with some pastel orange and light-blue t-wall, but can't find it  
  
Also  dustin , there is Golden Oldie 13 for you to check out :D  
and Also noticed other mixes from  Arno : the "earth slide" caves  
  
I haven't found other caves from BD1 besides intermissions

 darkstoorm , very interesting, thanks! :d  
  
i just checked the colors of the two caves you mentioned:  
  
golden oldie 7:  
color dirt: orange  
color twall: azure blue  
color bwall: yellow  
  
golden oldie 15:  
color dirt: azure blue (dark shade)  
color twall: greyish green  
color bwall: yellow  
  
notes:  
\ in g.o.7, the two main colors are rgb complements.  
\ you seem to prefer yellow bwall color, which is also my favourite beside classical white :d the ||| and \\\ look somewhat like shining little suns/ stars to me :d  
  
yep, i already checked the other caves from  Arno  :d

i think color schemes often look nice when:   
- 1 color is "bold"  
- 2 colors are more "modest" (greyish or brownish variants of a color)  
- background is black or very dark  
  
many times the amoeba/wall color is the most bold one. (example: golden oldie 2)  
  
golden oldie 7 is an example where the t-wall color is quite bold (whereas the dirt is more modest, and the slime yellow, but not too bright yellow).  
  
and in golden oldie 15 it is the dirt color (with modest t-wall and (again) not too bright yellow amoeba/slime).

 Arno , that comes close to complementary colors according to the hsv color model! :d  
  
h = hue (0 degrees=red, 120 deg = green, 240 deg = blue)  
s = saturation (this comes close to what you called "boldness"): a percentage value describing the grayness of a color. 0 percent = gray, 100 percent = one of the three basic colors is completely out  
v = value = percentage of the biggest basic color  
  
for example:  
  
golden oldie 7:  
color dirt: hex = #a3922f, h=51deg (orange), s = 71%, v = 64%  
color twall: hex = #0077b3, h = 200deg (azure), s = 100%, v = 70%  
brick wall: hex = #ffef94, h = 58deg (yellow), s = 43%, v = 99%  
  
golden oldie 15:  
color dirt: hex = #025599, h = 207deg (azure), s = 99%, v = 60%  
color twall: hex = #88a691, h = 138deg (nlueish green), s = 18%, v = 65%  
color bwall: hex = ffef94, h = 51deg (orange/yellow), s = 42%, v = 100%.  
  
comparing the saturation values, it can clearly be seen that there's one very saturated color with 99 or 100% while the other two are far more modest.  
  
perfect hsv complements would be two colors where:  
\ the hue differs by 180deg  
\ the s and v values add up to 100% each.  
  
more material for more color experiments! :d

interesting stuff! :-)  
  
i think both the s and v value together determine the "boldness" of a color. when both are 100% the color is most bold. lower values of any or both parameters makes the color more greyish (or "modest").  
  
it actually seems that the color picker here at  krissz ' site is based on the hsv model. the horizontal axis represents h, the vertical axis v, and the vertical bar at the right is used to pick s. this makes it very easy to play around with "perfect hsv complements". for instance, you can set the v to approx. 30% for one color and 70% for the other. this works fine, unless you want to be perfectly accurate with the percentages.

hmm, you're right, v also plays a role because if a color is dark in general, then it cannot be as "bold" as a lighter color.  
how about defining the "boldness" B as b=s*v? this would be especially easy to calculate from the hex code because it's just equal to the difference of the maximum and minimum out of the three rgb values:  
  
B := s*v = max(r,g,b) - min(r,g,b)  
  
for the aforementioned caves:  
  
Golden oldie 7:  
color 1: #a3922f, b = a3-2f = 74 (45%)  
color 2: #0077b3, B = b3-00 = b3 (70%)  
color 3: #fcf88f, B = vc-8f = 6d (43%)  
  
golden oldie 15:  
color 1: #025599, b = 99-02 = 97 (59%)  
color 2: #88a691, b = a6-88 = 1e (12%)  
color 3: #ffef94, B = ff-94 = 6b (42%)  
  
ok, for the percentages i needed a calculator, but they're actually not so necessary for comparison :d  
  
i just checked the color chooser in the ckit and yes, that's actually based on the hsv scheme. gdash also has such a hsv color chooser. it seems more intuitive than the rgb scheme because:  
\ there's only one value for the color itself (the hue h)  
\ and also it's better for only 2 dimensions the saturation is a good value to choose last, whereas with a rgb-based color chooser, it's not clear which value (r, g or b) should be the last one to choose.
