   code for cycling through hues (colors)
  anyone willing to share some code that cycles through through the color hue spectrumthanks zed   
  Funny, I just put this together yesterday. It's written for D3D9, but the only change you'd need to fit any other API is on the last line, converting R, G & B to your colour format.My code takes a hue in the range (0.0, 1.0), assumes your lightness and saturation are both fixed at 1.0 (maximum) and returns a RGB DWORD. To cycle using this function should be trivial.DWORD SaturatedHue(float Hue) {float r, g, b;r = Hue + 1.0f / 3;g = Hue;b = Hue - 1.0f / 3;if (r > 1) r -= 1;if (b < 0) b += 1;if (r < 0.16667f) {r = 1.0f - 6.0f * r;} else if (r < 0.5f) {r = 0;} else if (r < 0.66667f) {r = 6.0f * r - 3.0f;} else r = 1;if (g < 0.16667f) {g = 1.0f - 6.0f * g;} else if (g < 0.5f) {g = 0;} else if (g < 0.66667f) {g = 6.0f * g - 3.0f;} else g = 1;if (b < 0.16667f) {b = 1.0f - 6.0f * b;} else if (b < 0.5f) {b = 0;} else if (b < 0.66667f) {b = 6.0f * b - 3.0f;} else b = 1;return D3DCOLOR_ARGB(0xFF, (byte) (r * 0xFF), (byte) (g * 0xFF), (byte) (b * 0xFF));}It's not optimised and there's a fair bit of casting involved, but it's not exactly slow either. If you're using this a lot you may want to make some adjustments.If you need more control, Wikipedia documents the HSL-RGB conversion thoroughly.RegardsAdmiral   ;  You need to convert the colors to another color model (i.e. HSV). This allows easy shifting of the hue. Then convert the colors back.For the conversion see here:http://www.cs.rit.edu/~ncs/color/t_convert.html;  thanks guys sorry about being lazy, but i just wanna see if this looks better with my ingame menus than what i have at present, ie i didnt wanna spend time implimenting something that looks crap so i wouldnt use
