Textures

Hi, I need to impose a specific texture on the triangle primitives. So, I have a texture file: [attachment=13225:256colour3.png] And I have a list of triangle primitives. I build a surface of these triangles. Each of triangle point contain data: 1) position 2) texture coordinate Depands of texture coordinate on each point, I want to make color transition on the surface, like this:[attachment=13226:Capture1234.PNG] But, using this shader Texture ColorTexture; sampler ColorTextureSampler = sampler_state { texture = <ColorTexture> ; magfilter = NONE; minfilter = NONE; mipfilter = NONE; AddressU = wrap; AddressV = wrap; }; struct VertexShaderInput { float4 Position : POSITION; float2 texCoord : TEXCOORD0; }; struct VertexShaderOutput { float4 Position : POSITION; float2 texCoord : TEXCOORD0; }; float4x4 worldViewProj; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output = (VertexShaderOutput)0; output.Position = mul(input.Position, worldViewProj); output.texCoord = input.texCoord; return output; } float4 PixelShaderFunction(VertexShaderOutput input) : COLOR { return tex1D( ColorTextureSampler, input.texCoord.x); } technique Technique1 { pass Pass1 { VertexShader = compile vs_2_0 VertexShaderFunction(); PixelShader = compile ps_2_0 PixelShaderFunction(); } } I receive this: [attachment=13227:Capture1236.PNG] So, how should I modificate shader to receive such kind of color transition? Or, maybe, I should modificate texture file?
